This blog post proposes a novel concept - ETL-C, a context-first approach for building Data / AI platforms in the Generative AI dominant era. More discussions to follow.
Think of your data as a sprawling city.
Raw data is just buildings and streets, lacking the vibrant life that gives it purpose. ELT-C injects that vibrancy - the demographics, traffic patterns, and even the local buzz. With the added dimensions of Context Stores, your data city becomes a place of strategic insights and informed action.
As we develop an increasing number of generative AI applications powered by large language models (LLMs), contextual information about the organization’s in-house datasets becomes crucial. This contextual data equips our platforms to effectively and successfully deploy GenAI applications in real-world scenarios, ensuring they are relevant to specific business needs and tailored to the appropriate contexts.
Let’s explore how this integrated approach empowers data-driven decision-making.
Let’s recap the key ETL stages followed by the Contextualize:
Extract The “Extract” stage involves pulling data from its original sources. These could be databases, applications, flat files, cloud systems, or even IoT devices! The goal is to gather raw data in its various forms.
Load Once extracted, data is moved (“Loaded”) into a target system designed to handle large volumes. This is often a data warehouse, data lake, or a cloud-based storage solution. Here, the focus is on efficient transfer and storage, minimizing changes to the raw data.
Transform This stage is all about making data usable for analysis. Transformations could include:
Contextualize Contextualization is the heart of ELT-C, going beyond basic data processing and turning your information into a powerful analysis tool. It involves adding layers of information, including:
Metadata: Descriptive details about the data itself, such as where it originated, when it was collected, what data types are included, and any relevant quality indicators. This makes data easier to understand, catalog, and use.
External Data: Enriching your data by linking it to external sources. This might include:
User Data: Augmenting data with insights about how users interact with your products, services, or website. This could include:
Let’s see how the combination of metadata, external data, and user data could all be leveraged by a retail bank to optimize next-best credit card offers, with a focus on how contextualization enhances traditional approaches:
Metadata
External Data
User Data
Website behavior: Tracking user navigation paths to reveal buying intent or improve site design. Going beyond basic page views, contextualization could incorporate external economic data or user demographics to understand if browsing behavior is driven by necessity or changing financial priorities.
App engagement: Analyzing in-app behavior to identify churn indicators or opportunities to boost retention. Contextualize for Better Analysis: Adding LLM-derived sentiment analysis of user support queries within the app adds a new dimension to understanding pain points. This can reveal issues beyond technical bugs, potentially highlighting misaligned features or confusing user experience elements.
LLM engagement: Flowback LLM analytics data as in-house technical / business users and end-customers of your platform interact with other LLM applications. This could include insights on the types of queries, responses, and feedback generated within the LLM ecosystem. This is where ELT-C shines! LLM queries can be correlated with other user actions across systems. For instance, are users researching competitor offerings in the LLM, then browsing specific product pages on the bank’s site? This context highlights a customer considering alternatives and the need for urgent proactive engagement.
In image above, a Context Bridge that provides real time contexts across multiple publishers and subsribers. Context Stores can become even more powerful, when integrated with an Enterprise Knowledge Graph or Data Catalog (structured entity relationships meet flexible context stores for richer data analysis)
A Context Store is a centralized repository designed specifically for storing, managing, and retrieving contextual data. It extends the concept of feature stores to encompass a broader range of contextual information that can power rich insights and highly adaptive systems.
How Context Stores Elevate Context Management:

ASR8 | Maintainability and Extensibility | - Offers straightforward administration features for data updates or schema changes. - Can be easily extended to support new context types or integrate with evolving systems. |
Data isn’t just about numbers and values. Context adds the crucial “why” and “how” behind data points. Context stores have the potential to handle this richness, while vector stores specialize in representing relationships within data.
Let’s delve into these specialized tools.
Similarities
Key Differences
Feature | Context Store | Vector Store |
---|---|---|
Focus | Broad range of contxtual data | Numerical representations of data (embeddings) |
Data Types | Metadata, structured data, text, external data, embeddings | Primarily numerical vectors (embeddings) |
Search Methods | Metadata-based, text-based, feature searches | Similarity-based search using vector distances |
Primary Use Case | Powering analytics, ML models with rick context | Recommendations, semantic search, similarity analysis |
How They Can Work Together
Context stores and vector stores are often complementary in modern data architectures:
Embedding Storage: Context stores can house embeddings alongside other contextual data, enabling a holistic view for machine learning models.
Semantic Search: Vector stores enhance how context stores access information, allowing searches for contextually similar items based on their embeddings.
Enriching ML Features: Context stores provide a variety of data sources to inform the creation of powerful features for ML models. These features might then be transformed into embeddings and stored in the vector store.
Knowledge Graphs (KGs) and Context Stores can complement each other to significantly enhance how data is managed and utilized:
Contextualizing Knowledge Graphs: Context stores can provide KG entities with richer context. Imagine a KG entity for a “product”.
A context store might house information about a specific product launch event, user reviews mentioning the product, or real-time pricing data. This contextual data adds depth to the product entity within the KG.
Reasoning with Context: KGs enable reasoning over connected entities, considering the relationships within the graph. Context stores can provide real-time updates or specific details that influence this reasoning process. Think of a recommendation system that leverages a KG to understand user preferences and product relationships.
Real-time stock data from a context store could influence the recommendation engine to suggest alternative products if a preferred item is out of stock.
Enriching Context with Knowledge: KGs can act as a source of structured context for the data within a context store.
For instance, a context store might hold user search queries related to a particular topic. A KG could link these queries to relevant entities and their relationships, providing a more comprehensive understanding of user intent behind the searches. These queries can be in the form of the on-site / in-app LLM powered chat interactions too.
Imagine a customer support scenario where a user has a question about a product.
By working together:
GCP provides powerful tools to build a robust and sophisticated Context Store. By leveraging BigTable for scalable storage and versioning, and EKG for structured context, you create a system that supports rich analytics and adaptive machine learning models.
BigTable: Serves as the foundation for storing diverse contextual data types. Its high-performance, scalability, and native versioning are ideal for capturing both real-time updates and historical context.
Cloud Enterprise Knowledge Graph (EKG): EKG introduces a structured context layer. It manages entities, their relationships, and rich metadata. This allows you to connect and represent complex relationships within your data.
Pub/Sub: A reliable messaging service for ingesting real-time updates from various context sources like user behavior tracking, IoT sensors, or external data streams.
Cloud Dataflow: This fully-managed service cleans, transforms, and enriches streamed context data from Pub/Sub. Dataflow can link context data to EKG entities or derive features for BigTable storage.
Cloud IAM: Enforce fine-grained access controls on all GCP resources (BigTable, EKG, Pub/Sub) for security and compliance.
Imagine you’re a customer facing an issue with a product. Wouldn’t it be ideal if the support system understood your purchase history, knew the product’s intricacies, and could access the latest troubleshooting information? Let’s dive into an example of how a BigTable and EKG-powered Context Store makes this possible:
The classic Extract, Transform, Load (ETL) process has evolved to address the demands of modern data-driven organizations. By strategically incorporating the Contextualize (C) step at different points in the pipeline, we create several permutations. While in this post, We explored Contextualize(C) following an ETL step, the Context can be injected at any stage of the ETL process, and even multiple times.
Understanding these variations - ELT-C
, ELT-C
, EC-T
, and even EL-C-T-C
is key to designing a data pipeline that best aligns with your specific needs and data architecture. Let’s explore these permutations and their implications.
ETL-C (discussed in majority of this post above)
ELT-C
EL-C-T
EL-C-T-C
The optimal permutation depends on factors like:
ETL-C
is still valuable when clean, structured data is a hard requirement for downstream systems.EL-C-T
or EL-C-T-C
are valuable when context is derived from the raw data itself or needs to be updated alongside transformations.Do note that, these are not always strictly distinct. Modern data pipelines are often hybrid, employing elements of different patterns based on the specific data source or use case.
Scenario: Real-time Sentiment Analysis for Social Media
Challenge: Social media is a goldmine of raw customer sentiment, but extracting actionable insights quickly from its unstructured, ever-changing nature is complex.
How EL-C-T-C Helps:
Extract (E): A system continuously pulls raw social media data (posts, tweets, comments) from various platforms.
Load (L): The raw data is loaded directly into a scalable data lake for immediate accessibility.
Contextualize (C1): Initial contextualization is applied:
Transform (T):
Contextualize (C2): The transformed data is further enriched:
Outcome
The business has a dashboard that not only tracks the real-time sentiment surrounding their brand and products, but can drill down on the drivers of those sentiments. This data empowers them to proactively address customer concerns, protect brand reputation, and make data-informed product and marketing decisions.
Is ELT-C the right choice for your data workflows? If you’re looking to fully unlock the potential of your data, I recommend giving this framework a closer look. Begin by identifying areas where integrating more context could substantially improve your analytics or machine learning models.

]]>In the second installment of our three-part series on rethinking ETL processes through the lens of Large Language Models (LLMs), we shift our focus from the search for an optimal algorithm, covered in Part 1, to exploring practical examples and defining clear optimization goals.
Large Language Models have proven their potential in streamlining complex computational tasks, and their integration into ETL workflows promises to revolutionize how data is transformed and integrated.
Today, we will delve into specific examples that will form the building blocks of LLMs’ role in various stages of the ETL pipeline — from extracting data from diverse sources, transforming it for enhanced analysis, to efficiently loading it into final destinations. We will also outline key optimization goals designed to enhance efficiency, accuracy, and scalability within ETL processes. These goals will form target goals for out LLM Agents in the ETL Workflow design and optimization in Part 3.
Let’s start with some examples.
Consider a simplified ETL scenario where you have:
Cost Modeling We’ll assume the primary cost factor is the size of the dataset at each stage:
Heuristic Function
h(n)
: Estimates the cost to reach the goal (output dataset) from node nA* Search in Action
g(n)
of reaching the new node.h(n)
for the new node.f(n) = g(n) + h(n)
.Prioritization: The A* algorithm will favor exploring nodes with the lowest estimated total cost (f(n)
).
Example Decision
A* might prioritize an ETL path with early filtering, as the heuristic will indicate this gets us closer (in terms of data size) to the final output structure more quickly.
Input Datasets
Output Dataset
Available Operations
Cost Factors
Heuristic Function Possibilities
The A* search would traverse a complex graph. Decisions could include:
We can consider different heuristic approaches when designing our A* search for ETL optimization, along with the types of domain knowledge they leverage:
Schema-Based Similarity
Data Volume Reduction
Dependency Resolution
Error Risk Mitigation
Computational Complexity Awareness
Hybrid Heuristics
In complex ETL scenarios, you’ll likely get the best results by combining aspects of these heuristics. For instance: Prioritize early filtering to reduce data size, BUT check if it depends on fields that need cleaning first. Favor a computationally expensive join if it’s essential for generating multiple output fields and avoids several smaller joins later.
Consider the ETL operation in Banking, where we are building the Customer 360 degree view. The Data sources are the customer transactions from POS with Credit Card numbers need to be hashed before joining with the customer profile. Third Party datasets are also used to augment the customer profile, which are only available end of day. Datasets also include recent call center interaction view and past Campaigns /and offers prepared for the customer.
Dependency Resolution
Let’s design a heuristic specifically tailored for dependency resolution as our optimization goal.
Understanding the Scenario
Dependency Resolution Heuristic
Our heuristic h(n)
should estimate the cost to reach the final output dataset from node n
. Here’s a possible approach:
Domain Knowledge Required
Linking Fields: Precisely which fields form the basis for joins. Typical Data Volumes: Understanding which joins might be computationally more expensive due to dataset sizes.
Refinement
Although this heuristic is a good starting point, it can be further refined.
Resource Usage Minimization
Here’s a breakdown of factors we could incorporate into a heuristic h(n)
that estimates the resource usage impact from a given node n onwards:
Dataset Size Anticipation:
Memory-Intensive Operations: Identify operations likely to require large in-memory processing (complex sorts, joins with certain algorithms). Increase the cost contribution of nodes leading to those operations.
Network Bottlenecks: If data movement is a concern, factor in operations that involve transferring large datasets between systems. Increase the cost contribution for nodes where this movement is necessary.
Temporary Storage:
If some operations necessitate intermediate storage, include an estimate of the storage cost in the heuristic calculation.
Effective execution planning is key to optimizing performance and managing resources. Our approach involves dissecting the workflow into distinct nodes, each with unique characteristics and challenges. Let’s delve into the specifics of two critical nodes in our current pipeline, examining their roles and the anticipated heuristic costs associated with their operations.
Node A: Represents a state after filtering transactions down to a specific time period (reducing size) followed by a memory-intensive sort. The heuristic cost might be moderate (reduction bonus, but sort penalty).
Node B: Represents a state where a large external dataset needs to be joined, likely increasing dataset size and potentially involving data transfer. This node would likely have a higher heuristic cost.
Node A
To represent Node A mathematically, we can describe it using notation that captures the operations and their effects on data size and processing cost. Here’s a conceptual mathematical representation:
Let’s define:
Then, Node A can be represented as: \(A = s(f(D, t_1, t_2))\)
Here, \(f(D, t_1, t_2)\) reduces the size of \(D\) by filtering out transactions outside the specified time window, and \(s(X)\) represents a memory-intensive sorting operation on the filtered dataset. The overall cost \(C_A\) for Node A could be estimated by considering both the reduction in size (which decreases cost) and the sorting penalty (which increases cost). Mathematically, the cost might be represented as:
\[C_A = cost(f(D, t_1, t_2)) - reduction_bonus + cost(s(X)) + sort_penalty\]
This formula provides a way to quantify the heuristic cost of operations performed in Node A, taking into account both the benefits and penalties of the operations involved.
Node B
For Node B, which involves joining a large external dataset and possibly increases the dataset size and incurs data transfer costs, we can also set up a mathematical representation using appropriate functions and operations.
Let’s define:
Node B can then be represented as: \(B = j(D, E)\)
Here, \(j(D, E)\) represents the join operation that combines dataset \(D\) with external dataset \(E\), likely increasing the size and complexity of the data.
Considering the resource costs, particularly for data transfer and increased dataset size, we can mathematically represent the cost \(C_B\) for Node B as follows:
\[C_B = base_cost(D) + base_cost(E) + join_cost(D, E) + data_transfer_cost + size_penalty\]
This formulation provides a baseline framework to analyze the costs associated with Node B in your data processing pipeline.
Crucially, we may want to combine this resource-focused heuristic with our earlier dependency resolution heuristic. Here’s how we could do this:
- Weighted Sum:
h(n) = weight_dependency * h_dependency(n) + weight_resource * h_resource(n)
. Experiment with weights to find a balance between our optimization goals.- Conditional Prioritization: Perhaps use
h_dependency(n)
as the primary guide, but if two paths have similar dependency costs, then useh_resource(n)
as a tie-breaker.
As we continue to optimize our ETL processes, it’s crucial to consider how we can further enhance the efficiency and cost-effectiveness of our operations (beyond the hyrbid approaches discussed). There are several key areas where further refinements could prove beneficial. Let’s explore how targeted adjustments might help us manage resources better and smooth out any recurring bottlenecks in our processes.
In the final iteration, we will explore how to integrate Large Language Models (LLMs) as agents to enhance various aspects of the ETL optimization process we’ve been discussing.
Welcome to the first installment of our three-part series exploring the transformative impact of Large Language Models (LLMs) on ETL (Extract, Transform, Load) processes. In this opening segment, we focus on the search for an optimal algorithm for ETL planning.
As businesses increasingly rely on vast amounts of data to make critical decisions, the efficiency and effectiveness of ETL processes become paramount. Traditional methods often fall short in handling the complexity and scale of modern data environments, necessitating a shift towards more sophisticated tools.
In this part, we delve into how traditional algorithms can be used to design the planning stage of ETL workflows — we identify algorithms that are not only more efficient but also capable of handling complex, dynamic data scenarios. We will explore the foundational concepts behind these algorithms and discuss how they can be tailored to improve the entire data transformation and integration cycle.
Join us as we begin our journey into rethinking ETLs with the power of advanced language models, setting the stage for a deeper dive into practical applications and optimization strategies in the subsequent parts of the series.
Before diving into algorithms, let’s clarify the core elements:
Here’s a foundational outline of the algorithm, which we’ll refine for optimality:
Graph Construction:
Cost Assignment:
Search/Optimization:
Algorithm Pseudocode (Illustrative)
function plan_ETL_steps(input_dataset, output_dataset, available_operations):
graph = create_graph(input_dataset, output_dataset, available_operations)
assign_costs(graph)
optimal_path = dijkstra_search(graph, start_node, end_node)
return optimal_path
We’ll start by defining a simple class for a graph node that includes basic attributes like node name and any additional data that describes the dataset state at that node.
class GraphNode:
def __init__(self, name, data=None):
self.name = name
self.data = data # Data can include schema, size, or other relevant details.
self.neighbors = [] # List of tuples (neighbor_node, cost)
def add_neighbor(self, neighbor, cost=1):
self.neighbors.append((neighbor, cost))
def __str__(self):
return f"GraphNode({self.name})"
The Edges must include multiple costs and a probability for each cost. This would typically involve storing each cost along with its probability in a tuple or a custom object.
Multiple costs can represent the computation cost ($) which can have probability in terms of spot-instances of compute available vs committed instances. These computation costs determination can be defined by the priority of the ETL pipeline, e.g. a pipeline / step that generates an end of day compliance report may need a more deterministic behavior and consequently a higher cost for committed computed instances.
class Edge:
def __init__(self, target, costs, probabilities):
self.target = target
self.costs = costs # List of costs
self.probabilities = probabilities # List of probabilities for each cost
This function simulates the creation of intermediate nodes based on hypothetical operations. Each operation affects the dataset, potentially creating a new node:
def create_graph(input_dataset, output_dataset, available_operations):
start_node = GraphNode("start", input_dataset)
end_node = GraphNode("end", output_dataset)
nodes = [start_node]
# Placeholder for a more sophisticated operations processing
current_nodes = [start_node]
for operation in available_operations:
new_nodes = []
for node in current_nodes:
# Generate a new node for each operation from each current node
intermediate_data = operation['apply'](node.data) # Hypothetical function to apply operation
new_node = GraphNode(f"{node.name}->{operation['name']}", intermediate_data)
node.add_neighbor(new_node, operation['cost'])
new_nodes.append(new_node)
# Update current nodes to the newly created nodes
current_nodes = new_nodes
nodes.extend(new_nodes)
# Connect the last set of nodes to the end node
for node in current_nodes:
node.add_neighbor(end_node, 1) # Assuming a nominal cost to reach the end state
return start_node, end_node, nodes
To simulate realistic ETL operations, we define each operation with a function that modifies the dataset (simplified for this example):
def apply_cleaning(data):
return f"cleaned({data})"
def apply_transformation(data):
return f"transformed({data})"
available_operations = [
{'name': 'clean', 'apply': apply_cleaning, 'cost': 2},
{'name': 'transform', 'apply': apply_transformation, 'cost': 3}
]
Since each edge includes multiple costs with associated probabilities, the comparison of paths becomes probabilistic. We must determine a method to calculate the “expected” cost of a path based on the costs and their probabilities. The expected cost can be computed by summing the products of costs and their corresponding probabilities.
We need to redefine the comparison of paths in the priority queue to use these expected values, which involves calculating a composite cost that considers all probabilities.
import heapq
def calculate_expected_cost(costs, probabilities):
return sum(c * p for c, p in zip(costs, probabilities))
def dijkstra(start_node):
# Initialize distances with infinity
inf = float('infinity')
distances = {node: inf for node in all_nodes}
distances[start_node] = 0
# Priority queue holds tuples of (expected_cost, node)
priority_queue = [(0, start_node)]
visited = set()
while priority_queue:
current_expected_cost, current_node = heapq.heappop(priority_queue)
if current_node in visited:
continue
visited.add(current_node)
for edge in current_node.edges:
new_expected_cost = current_expected_cost + calculate_expected_cost(edge.costs, edge.probabilities)
if new_expected_cost < distances[edge.target]:
distances[edge.target] = new_expected_cost
heapq.heappush(priority_queue, (new_expected_cost, edge.target))
return distances
Example Execution
Here’s we might set up an example run of the above setup:
input_dataset = "raw_data"
output_dataset = "final_data"
start_node, end_node, all_nodes = create_graph(input_dataset, output_dataset, available_operations)
path, cost = dijkstra_search(start_node, end_node)
print("Optimal path:", path)
print("Total cost:", cost
This example demonstrates generating intermediate nodes dynamically as a result of applying operations in an ETL workflow. In a real application, the operations and their impacts would be more complex, involving actual data transformations, schema changes, and potentially conditional logic to decide which operations to apply based on the data’s characteristics or previous processing steps.
Creating a Domain-Specific Language (DSL) for modeling and specifying ETL (Extract, Transform, Load) processes can greatly simplify designing and implementing complex data workflows, particularly when integrating with a system that dynamically generates an ETL graph as previously discussed. Here’s an outline for a DSL that can describe datasets, operations, and their sequences in an ETL process:
The DSL will consist of definitions for datasets, operations (transforms and actions), and workflow sequences. Here’s an example of what each component might look like in our DSL:
Datasets are defined by their names and potentially any metadata that describes their schema or other characteristics important for transformations.
dataset raw_data {
source: "path/to/source/file.csv"
schema: {id: int, name: string, value: float}
}
dataset intermediate_data {
derived_from: raw_data
schema: {id: int, name: string, value: float, cleaned_value: float}
}
dataset final_data {
derived_from: intermediate_data
schema: {id: int, name: string, final_value: float}
}
Operations can be transformations or any kind of data processing function. Each operation specifies input and output datasets and may include a cost or complexity rating.
operation clean_data {
input: raw_data
output: intermediate_data
cost: 2
function: apply_cleaning
}
operation transform_data {
input: intermediate_data
output: final_data
cost: 3
function: apply_transformation
}
A workflow defines the sequence of operations applied to turn raw data into its final form.
workflow main_etl {
start: raw_data
end: final_data
steps: [clean_data, transform_data]
}
Let’s dive deeper into how to choose the best search algorithm for planning our ETL process. Recall that our core task involves finding the optimal (likely the lowest cost) path through the graph of datasets and ETL operations. While we defined a modified, Djiktra’s algorithm for variable and probabilistic costs, for discussion below we will use single aggregated weights.
Absolutely, let’s dive deeper into how to choose the best search algorithm for planning your ETL process. Recall that our core task involves finding the optimal (likely the lowest cost) path through the graph of datasets and ETL operations.
Dijkstra’s Algorithm:
O(|V|²)
in a simple implementation, but can be improved to O(|E| + |V|log|V|)
using priority queues. |V| = number of nodes (datasets)
, |E| = number of edges (ETL operations)
.A* Search
Genetic Algorithms
Size and Complexity of the ETL Graph: For smaller graphs, Dijkstra’s might be sufficient. Large, complex graphs might benefit from A* or genetic algorithms.
Importance of Optimality: If guaranteeing the absolute least cost path is critical, Dijkstra’s is the safest bet. If near-optimal solutions are acceptable, A* or genetic algorithms could provide faster results.
Availability of Heuristics: A* search heavily depends on having a good heuristic function. In ETL, a heuristic could estimate the remaining cost based on the types of operations needed to reach the final dataset structure.
Resource Constraints: Genetic algorithms can be computationally expensive. If runtime or available resources are limited, Dijkstra’s or A* might be more practical.
Imagine your goal is to minimize data volume throughout the process. A heuristic for A* search could be:
In the next iteration of this series, we will walkthrough examples of ETL scenarios, leveraging A* Star algorithm above and explore various optimization goals.
]]>In domains like real-time analytics, trend monitoring, and exploratory data analysis, the following often hold:
Let’s explore some key categories of approximate big data calculations:
Sampling
Sketching
Synopsis Data Structures
Approximation techniques often come with provable accuracy guarantees. Key concepts include:
Successful use of approximate calculations often lies in selecting the right technique and understanding its trade-offs, as different algorithms may offer varying levels of accuracy, space efficiency, and computational cost.
The embrace of approximation techniques marks a shift in big data analytics. By accepting a calculated level of imprecision, we gain the ability to analyze datasets of previously unmanageable size and complexity, unlocking insights that would otherwise remain computationally out of reach.
Big data calculations traditionally involve exact computations, where every data point is processed to yield precise results. This approach is comprehensive but can be highly resource-intensive and slow, especially as data volumes increase. In contrast, approximate calculations leverage statistical and probabilistic methods to deliver results that are close enough to the exact values but require significantly less computational power and time. Here’s a practical example comparing the two approaches:
Scenario: A large retail chain wants to calculate the average amount spent per customer transaction over a fiscal year. The dataset includes millions of transactions.
Method:
Scenario: The same retail chain adopts an approximate method to calculate the average spend per customer transaction to reduce computation time and resource usage.
Method:
In summary, while traditional methods ensure precision, approximate calculations provide a pragmatic approach in big data scenarios where speed and resource management are crucial. Choosing between these methods depends on the specific requirements for accuracy versus efficiency in a given business context.
We first generate a random transaction dataset of shopping purchases by customers. The dataset contains 3 columns, time of transaction, customer id and transaction amount. The number of customers is less than the total transactions, allowing to emulate multiple purchases by returning customer.
import random
import pandas as pd
from datetime import datetime, timedelta
import numpy as np
def generate_data(num_entries):
# Start date for the data generation
start_date = datetime(2023, 1, 1)
# List to hold all entries
data = []
max_customers_count = int(num_entries/(random.randrange(10, 100)))
for _ in range(num_entries):
# Generate a random date and time within the year 2023
random_number_of_days = random.randint(0, 364)
random_second = random.randint(0, 86399)
date_time = start_date + timedelta(days=random_number_of_days, seconds=random_second)
# Generate a hexadecimal Customer ID
customer_id = "cust_" + str(random.randrange(1, max_customers_count))
# Generate a random transaction amount (e.g., between 10.00 and 5000.00)
transaction_amount = round(random.uniform(10.00, 5000.00), 2)
# Append the tuple to the data list
data.append((date_time, customer_id, transaction_amount))
return data
We then define the sampling of the dataset, currently set a 1% of total size, i.e. for 100,000 ~ sampled 1,000
# Function to sample the DataFrame
def sample_dataframe(dataframe, sample_fraction=0.01):
# Sample the DataFrame
return dataframe.sample(frac=sample_fraction)
def calculate(df):
# Calculate the average transaction amount
average_transaction_amount = df['TransactionAmount'].mean()
# Calculate the average number of transactions per customer
average_transactions_per_customer = df['CustomerID'].count() / df['CustomerID'].nunique()
return average_transaction_amount, average_transactions_per_customer
We finally, run the whole expermient, i.e. generate dataset, run calculation multiple times. Here, num_experiments = 100
# Number of entries to generate
num_entries = 100000
tx_exact=[]
tx_approx=[]
num_experiments = 100
for i in range(0, num_experiments):
# Generate the data
transaction_data = generate_data(num_entries)
# Convert the data to a DataFrame
df = pd.DataFrame(transaction_data, columns=['DateTime', 'CustomerID', 'TransactionAmount'])
# Sample the DataFrame
df_sampled = sample_dataframe(df)
tx_exact.append(calculate(df)[0])
tx_approx.append(calculate(df_sampled)[0])
Finally we plot the Exact vs Approximate values. Mind the exaggerated spread out, because of the scaled plot.
percent_error = []
for i in range(num_experiments):
percent_error.append(abs(tx_exact[i]-tx_approx[i])/tx_exact[i])
from statistics import mean
print(mean(percent_error))
Upon further calculation you can see the relative percentage error across 100 experiments
runs and 100,000 transactions per experiment
the error is only order of 1.46%
(small error tradeoff for large scale of compute saved). The magnitude of the error would converge to zero as the number of transactions increase (which is typically the case when you are dealing with big data)
This section of our blog is dedicated to demonstrating how these powerful data structures—Bloom Filters, Count-Min Sketches, HyperLogLog, Reservoir Sampling, and Cuckoo Filters—can be practically implemented using Python to manage large datasets effectively. We will generate random datasets and use these structures to perform various operations, comparing their outputs and accuracy. Through these examples, you’ll see firsthand how probabilistic data structures enable significant scalability and efficiency improvements in data processing, all while maintaining a balance between performance and precision.

Overall Assessment
The number of possible execution plans grows exponentially as the complexity of a query increases. With many tables and joins, it becomes impossible for the database engine to exhaustively evaluate every plan to find the truly optimal one. Traditional optimizers often rely on heuristics that might lead to good, but not perfect, plans.
Genetic algorithms (GAs) mimic evolutionary principles to find near-optimal solutions within huge search spaces. Here’s how they apply to query optimization:
Representation (Chromosomes): Each possible execution plan is encoded as a ‘chromosome’. This could be a tree-like structure representing the order of joins and operations, an array representing index selection, etc.
Initial Population: The GA starts with a population of randomly generated chromosomes (execution plans).
Fitness Function: The key is defining a way to score the ‘fitness’ of a plan. Typically, this uses the database engine’s cost estimation to calculate the estimated execution time or resource usage.
Selection: Fitter chromosomes (those with lower estimated costs) have a higher probability of being selected for ‘reproduction’.
Crossover: Selected chromosomes are combined. For example, parts of the tree structures representing two plans might be swapped to create new plans. This combines potentially good aspects of multiple candidate solutions
Mutation: Random changes are introduced into some chromosomes. This helps avoid getting stuck in a local optimum and promotes exploration of the search space.
Iterative Evolution: The steps of selection, crossover, and mutation are repeated over multiple generations. The average fitness of the population should improve over time.
Below is an initial class repr of the query optimizer funtion. It assumes a Postgres implementation, and 3 table joins, e.g. Customer, Products, Transactions. More complex representations can be taken up, to accurately reflect real-world formultations. But, for now, lets proceed with a simplified approach.

chromosome_representation
function in the PostgresQueryOptimizer
class can be modified to incorporate indexes and sort orders into our execution plan optimization. The above array-based representation is modified below to include additional elements for index and sort considerations:
def chromosome_representation(self, query):
# ... (Existing join order and join methods logic) ...
# Index Selection (One decision per table)
for table in ["customer", "product", "transaction"]:
# Assume you have a way to determine relevant indexes for the table
available_indexes = get_available_indexes(table)
chromosome.append(random.choice(available_indexes + ["NO_INDEX"]))
# Sort Orders (One decision per join, if applicable)
for join_index in range(len(chromosome) - 3): # Only if multiple joins
# Assume you know on which columns of a table sorting is relevant
relevant_columns = get_relevant_sort_columns(chromosome[join_index])
chromosome.append(random.choice(relevant_columns + ["NO_SORT"]))
return chromosome
Updates
Index Selection: For each table, we randomly select from available indexes using a function called get_available_indexes
(we’d need to implement this based on how we retrieve index information from Postgres). We include "NO_INDEX"
as an option.
Sort Orders: For each join (if applicable), we determine relevant columns for sorting with a function get_relevant_sort_columns
(implementation also required). A "NO_SORT"
option signifies no explicit sorting on the join result.
Example Chromosome [('customer', 'product'), 'HJ', ('transaction', 'customer'), 'NL', 'idx_customer_name', 'NO_INDEX', 'idx_product_id', 'customer_id', 'NO_SORT']
Additional considerations
Helper Functions: we would need to also implement
get_available_indexes(table)
: A function to fetch the list of available indexes for a given table in Postgres.get_relevant_sort_columns(join_tuple)
. This function would determine which columns are relevant for sorting based on the joined tables and the query conditions.We’ve journeyed from the inspiration behind genetic algorithms to their transformative power in database query optimization. This two-part series highlights the potential for not just personalization, but also for accelerating your analytics and decision-making through streamlined database performance. The future of data platforms promises to be one where intelligent algorithms work hand-in-hand with traditional database structures.
]]>The image illustrates a genetic algorithm’s example iteration of the genetic algorithm with a population of three individuals, each consisting of four genes, showing steps from initial population generation through fitness measurement, selection, reproduction, mutation, and elitism, culminating in a new generation.
Genetic algorithms operate based on a few key principles derived from biological evolution:
The operation of a genetic algorithm can be described mathematically as follows:
New Generation Creation:
Selection: Select individuals based on their fitness scores to form a mating pool. Selection strategies might include tournament selection, roulette wheel selection, or rank selection.
\[P_{selected} = select(P(t), f)\]Crossover: Apply the crossover operator to pairs of individuals in the mating pool to form new offspring, which share traits of both parents.
\[offspring = crossover(parent_{1}, parent_{2})\]Mutation: Apply the mutation operator with a small probability 𝑝𝑚pm to each new offspring. This introduces randomness into the population, potentially leading to new solutions.
\[offspring = mutate(offspring, p_{m})\]Replacement: The new generation 𝑃(𝑡+1)replaces the old generation, and the algorithm repeats from the fitness evaluation step until a stopping criterion is met (like a maximum number of generations or a satisfactory fitness level).
In a data management context, GAs can be applied to several critical areas:
Genetically-Inspired Data Platforms represent a sophisticated approach to optimizing data management tasks through evolutionary principles. By leveraging genetic algorithms, these platforms can adapt and optimize themselves in ways that traditional systems cannot match, especially in complex and dynamic environments. This approach offers a promising avenue for enhancing the efficiency and performance of data platforms, albeit with considerations for the inherent complexities and computational demands of genetic algorithms.
Building a Genetically-Inspired Data Platform introduces several key differentiators that set it apart from traditional data management systems. These differentiators leverage the unique capabilities of genetic algorithms (GAs) to adapt, optimize, and evolve data management tasks dynamically. Here are some of the essential aspects that make these platforms stand out:
1. Adaptive Optimization
2. Automated Problem-Solving
3. Scalability and Efficiency
4. Robustness and Resilience
5. Innovation Through Genetic Diversity
6. Sustainability
7. Customization and User Involvement
Let’s have a quick look at how Generic Algorithms (GAs) can contribute to one of the most common use cases of a traditional use cases for ecommerce.
At their core, genetic algorithms are inspired by the principles of natural selection and evolution. Here’s a simplified analogy:
Dynamic Optimization: GAs excel at finding optimal solutions in complex, ever-changing environments. In e-commerce, recommendations must constantly adapt to:
Handling Massive Parameter Spaces: Recommendation systems work with a huge number of factors affecting suggestion accuracy:
Implicit Feedback: GAs can subtly improve recommendations based on things users don’t explicitly do. For example:
This is for illustrative purposes. Real-world data would be far more complex, involving thousands of users, products, and interactions. We’ll focus on easily understandable key performance indicators (KPIs). Real systems often track many more metrics.
An e-commerce platform conducts an A/B test for 1 month across a segment of its user base.

Explanation of the parameters and terms used in the context of the RecommenderGA
class:
Population
In the context of a genetic algorithm, the population refers to a group of potential solutions to the problem at hand. Each solution, also known as an individual in the population, represents a different set of parameters or strategies. In the RecommenderGA
class, each solution is a different weighting scheme for various factors that influence recommendations. The size of the population determines the diversity and coverage of possible solutions, which directly influences the genetic algorithm’s ability to explore the solution space effectively.
Chromosome
A chromosome in genetic algorithms represents an individual solution encoded as a set of parameters or genes. In the RecommenderGA
class, an example chromosome like [0.3, 0.5, 0.1, 0.1] could represent the weights assigned to different recommendation factors:
These weights determine how each factor contributes to the recommendation score for a particular item, influencing the final recommendations presented to users.
Fitness Function
The fitness function is a critical component of genetic algorithms used to evaluate how good a particular solution (or chromosome) is at solving the problem. It quantifies the quality of each individual, guiding the selection process for breeding. In recommendation systems, a fitness function could consider multiple factors like:
These metrics help determine the effectiveness of different weighting schemes in improving business outcomes and user engagement.
Crossover
Crossover is a genetic operator used to combine the information from two parent solutions to generate new offspring for the next generation, aiming to preserve good characteristics from both parents. It involves swapping parts of two chromosomes. For example:
A possible offspring after crossover could be [0.3, 0.3, 0.3, 0.1], taking parts from both parents. This process is intended to explore new areas of the solution space by combining successful elements from existing solutions.
Mutation
Mutation introduces random changes to the offspring’s genes, helping maintain genetic diversity within the population and allowing the algorithm to explore a broader range of solutions. It helps prevent the algorithm from settling into a local optimum early. In the example:
This slight alteration in the weights might lead to discovering a more effective combination of factors that wasn’t present in the initial population.
Together, these components facilitate the genetic algorithm’s ability to optimize complex problems by simulating evolutionary processes, making it a robust tool for developing sophisticated recommendation systems.
Fitness Functions
For realistic fitness functions for both the Genetic Algorithm (GA) based recommender and the Classical Algorithm (Collaborative Filtering) based recommender, we’ll need to define more specific fitness functions. Let’s assume these fitness functions consider factors such as user engagement, revenue, or any other metric relevant to recommendation quality.
Example usage
# Example usage
ga_population_size = 10
num_items = 100 # Total number of items
num_features = 4 # Number of features per item
num_recommendations = 5 # Number of recommendations to generate
num_days = 30 # Duration of the A/B test
test = ECommerceABTest(ga_population_size, num_items, num_features, num_recommendations, num_days)
test.run_test()
results = test.get_results()
print(results)

This data provides a clear comparison over the 30-day period, showing consistently higher performance by the GA-based recommender compared to the collaborative filtering recommender, indicating a potential advantage of the GA approach in optimizing recommendations.
The plot showing the comparison of average fitness scores over a 30-day period for both the Genetic Algorithm (GA) based recommender and the Collaborative Filtering (CF) based recommender. As illustrated, the GA-based system shows a trend of improving fitness, indicating adaptation and optimization over time, whereas the CF-based system shows more variability with generally lower scores.

]]>This post delves into the complex world of computational complexity in data management, comparing and contrasting classical approaches with their quantum counterparts. As we explore the mechanics and implications of Grover’s Algorithm, we will uncover how quantum computing is not just a theoretical exercise but a practical tool poised to transform the data management industry. Read through with me, as we navigate through the intricate details of these computing paradigms and their potential to reshape our understanding and handling of data in an increasingly digital world.
In traditional data platforms, core database operations exhibit the following ‘common’ complexities:
Searching: Unsorted data typically requires linear search algorithms with complexity O(n)
, where n
is the size of the dataset. Sorted datasets can use binary search, achieving O(log n)
. However, more advanced indexing structures like B-trees further reduce this complexity.
Insertion/Deletion: These operations, especially in sorted environments, tend to have O(n)
complexity as data may need to be shifted. Balanced trees can reduce this to O(log n)
.
Complex Queries and Joins: The complexity of these operations depends on the algorithms used and data structures. Nested-loop joins can reach O(n²)
, while optimized hash joins or merge joins can be closer to O(n log n)
or even O(n)
with suitable structures.
Quantum Data Management Platforms introduce groundbreaking algorithms with potentially significant advantages:
It’s crucial to highlight several points:
Let’s illustrate with a concrete example — searching for a specific item in a database:
O(n)
O(√n)
If our database has a billion entries (n = 1,000,000,000), a traditional search might take a billion steps on average. Grover’s algorithm could potentially find the item in roughly 30,000 steps — a dramatic difference.
Let’s break down how Grover’s algorithm achieves this impressive search efficiency. It’s important to note that Grover’s algorithm, at its heart, doesn’t directly search a database in the traditional sense; it instead solves the following kind of problem:
Problem: You have a function (often called an ‘oracle’) that takes an input and outputs ‘1’ if the input is your desired solution and ‘0’ otherwise. Your goal is to find an input that makes the function produce a ‘1’.
Here’s the core idea behind Grover’s algorithm, presented in a simplified way:
Step 1. Superposition: Instead of examining database entries one at a time, Grover’s leverages quantum superposition. The algorithm puts a quantum system into a superposition representing all possible database entries equally.
Step 2. Oracle Marking: The oracle function is applied in a quantum way, causing it to ‘mark’ the correct entry by negating its amplitude (think of flipping its sign).
Step 3. Amplitude Amplification: The key step — Grover’s algorithm uses an operation called ‘diffusion’ to amplify the amplitude of the marked entry. Intuitively, this makes it “stand out” from the crowd of other entries.
Step 4. Iteration: Steps 2 and 3 are repeated multiple times. Each iteration amplifies the correct answer further.
Interference: The amplitude amplification step uses quantum interference to cleverly increase the probability of measuring the correct answer while simultaneously decreasing the probability of measuring incorrect ones. Success Probability: After a specific number of iterations (roughly the square root of the number of entries), the probability of measuring the correct solution becomes very high.
Analogy
Think of a lottery with a billion tickets, but only one winner. Normally, you’d check tickets one by one. Grover’s does something akin to:
With a billion entries (n = 1,000,000,000), the square root of n is approximately 31,622. This roughly aligns with the 30,000 steps mentioned. Importantly, the number of steps in Grover’s algorithm doesn’t grow at the same rate as a traditional search.
Important Notes
Grover’s algorithm’s power lies in its core operation — amplitude amplification. Let’s delve into the mathematical details of this critical step.
Setting the Stage: Hilbert Space and Notation
|s⟩ = (|0⟩ + |1⟩)/√2
(for single qubit) or a similar equal superposition for n qubits.The Magic: Amplitude Amplification Operator
The key operator in Grover’s diffusion is the Grover operator, denoted as G. It’s constructed using the reflection operator, R:
R = 2|s⟩⟨s⟩ — I
(where I is the identity operator)
The Grover operator, G, is then defined as:
G = R — (2|0⟩⟨0⟩ + 2|1⟩⟨1⟩) = R — 2I
Understanding the Operators
R reflects the current state around the uniform superposition | s⟩. |
The Amplification Process
Now comes the magic! We apply the oracle (O) followed by the Grover operator (G) in a loop:
|ψ⟩ = G * O |s⟩
This sequence (GO) cleverly amplifies the amplitude of the desired solution state while diminishing those of incorrect entries.
Iterative Amplification
Repeating the sequence (GO) multiple times enhances this amplification effect.
Mathematically, after t
iterations:
|ψ_t⟩ = (GO)^t |s⟩
Finding the Optimal Number of Iterations
The number of iterations (t) for optimal amplification depends on the number of entries (n). Here’s the sweet spot:
t ≈ √(π * n / 4)
With this number of iterations, the probability of measuring the desired solution becomes very high.
Inner Workings: A Geometric View
Imagine the initial state as a vector in the n-dimensional Hilbert space. The oracle “marks” the solution by rotating it. Subsequent applications of the Grover operator act like further rotations, amplifying the solution’s projection onto the desired subspace while diminishing those of incorrect entries.
Complexity Analysis
The number of iterations (t) scales as the square root of n, a significant improvement over the linear search complexity (O(n)). This translates to the dramatic speedup observed in Grover’s algorithm.
By leveraging the power of quantum superposition, oracle marking, and the Grover operator’s clever manipulation of amplitudes, Grover’s algorithm achieves an exponential speedup for search problems in unstructured databases.
While implementing this in real-world quantum computers presents challenges, the theoretical foundation of amplitude amplification provides a fascinating glimpse into the potential of quantum algorithms.

QEC remains a significant challenge. Efficient use of quantum data systems requires ongoing advancements in error correction techniques to maintain the integrity and reliability of data operations.
Imagine you’re building a sandcastle on a windy beach. No matter how intricate or beautiful, a single gust can come along and mess it all up. That’s kind of what happens in quantum computers. They use quantum bits, or qubits, to store information, but these qubits are susceptible to errors from their environment.
