Building an NBA Stats Pipeline with AWS, Python, and DynamoDB

This tutorial details the creation of an automated NBA statistics data pipeline using AWS services, Python, and DynamoDB. Whether you're a sports data enthusiast or an AWS learner, this hands-on project provides valuable experience in real-world data processing.

Project Overview

This pipeline automatically retrieves NBA statistics from the SportsData API, processes the data, and stores it in DynamoDB. The AWS services used include:

• DynamoDB: Data storage
• Lambda: Serverless execution
• CloudWatch: Monitoring and logging

Prerequisites

Before starting, ensure you have:

• Basic Python skills
• An AWS account
• The AWS CLI installed and configured
• A SportsData API key

Project Setup

Clone the repository and install dependencies:

<code class="language-bash">git clone https://github.com/nolunchbreaks/nba-stats-pipeline.git
cd nba-stats-pipeline
pip install -r requirements.txt</code>

Environment Configuration

Create a .env file in the project root with these variables:

<code>SPORTDATA_API_KEY=your_api_key_here
AWS_REGION=us-east-1
DYNAMODB_TABLE_NAME=nba-player-stats</code>

Project Structure

The project's directory structure is as follows:

<code>nba-stats-pipeline/
├── src/
│   ├── __init__.py
│   ├── nba_stats.py
│   └── lambda_function.py
├── tests/
├── requirements.txt
├── README.md
└── .env</code>

Data Storage and Structure

DynamoDB Schema

The pipeline stores NBA team statistics in DynamoDB using this schema:

• Partition Key: TeamID
• Sort Key: Timestamp
• Attributes: Team statistics (win/loss, points per game, conference standings, division rankings, historical metrics)

AWS Infrastructure

DynamoDB Table Configuration

Configure the DynamoDB table as follows:

• Table Name: nba-player-stats
• Primary Key: TeamID (String)
• Sort Key: Timestamp (Number)
• Provisioned Capacity: Adjust as needed

Lambda Function Configuration (if using Lambda)

• Runtime: Python 3.9
• Memory: 256MB
• Timeout: 30 seconds
• Handler: lambda_function.lambda_handler

Error Handling and Monitoring

The pipeline includes robust error handling for API failures, DynamoDB throttling, data transformation issues, and invalid API responses. CloudWatch logs all events in structured JSON for performance monitoring, debugging, and ensuring successful data processing.

Resource Cleanup

After completing the project, clean up AWS resources:

<code class="language-bash">git clone https://github.com/nolunchbreaks/nba-stats-pipeline.git
cd nba-stats-pipeline
pip install -r requirements.txt</code>

Key Takeaways

This project highlighted:

1. AWS Service Integration: Effective use of multiple AWS services for a cohesive data pipeline.
2. Error Handling: The importance of thorough error handling in production environments.
3. Monitoring: Essential role of logging and monitoring in maintaining data pipelines.
4. Cost Management: Awareness of AWS resource usage and cleanup.

Future Enhancements

Possible project extensions include:

• Real-time game statistics integration
• Data visualization implementation
• API endpoints for data access
• Advanced data analysis capabilities

Conclusion

This NBA statistics pipeline demonstrates the power of combining AWS services and Python for building functional data pipelines. It's a valuable resource for those interested in sports analytics or AWS data processing. Share your experiences and suggestions for improvement!
