Event-Driven ETL Data Pipeline for Loading Shipments to Redshift
Event-Driven Data Pipeline for Shipments Data Extraction,Processing and Loading into Redshift.
I have built an event-driven data pipeline using AWS services to automate the extraction, transformation, and loading (ETL) of shipments data from an API into Amazon Redshift, leveraging a serverless architecture. Deployed the solution using an Azure DevOps CI/CD pipeline and AWS CloudFormation for infrastructure provisioning.
About Client:
I served as a Cloud Solution Architect and Lead Data Engineer for a prominent Healthcare and Wellness brand, Wellbeam Health Org, based in San Francisco. In this full-time role, I successfully completed the project while navigating and overcoming numerous complex challenges and technical issues throughout the development process
Technologies Used:
AWS Services: EventBridge, Lambda, S3, SQS, Redshift, CloudFormation, IAM.
Azure DevOps: Pipelines for CI/CD, versioning, and deployments.
Programming: Python (with libraries for API interaction, data transformation, and Redshift integration).
Database: Amazon Redshift for analytics and reporting.
Infrastructure as Code (IaC): AWS CloudFormation templates.
Local Testing and Debuging: AWS CLI, SAM CLI, Terraform, Local Stack, Make.
Architecture and Workflow:
EventBridge Scheduler:
Configured AWS EventBridge to trigger the workflow daily.
Ensures the timely extraction of shipments data from the API.
First Lambda Function (Data Extraction):
Extracts data from the Shipments Data API.
Saves:
Raw version of the data into the Data Ingestion S3 Bucket.
Transformed version of the data into the Processed Data S3 Bucket.
S3 to SQS Notification:
Configured the Processed Data S3 Bucket to send notifications to an SQS Queue whenever new files are added.
Ensures decoupled and reliable processing.
Second Lambda Function (Data Loading):
Triggered by the SQS Queue.
Loads the transformed data from the Processed Data S3 Bucket into Amazon Redshift using the COPY command.
AWS CloudFormation:
Automated provisioning of all AWS resources (EventBridge, Lambda functions, S3 buckets, SQS queues, Redshift cluster, IAM roles, etc.).
Azure DevOps CI/CD Pipeline:
Used to package, build, and deploy Lambda functions and CloudFormation templates.
Integrated with Git for version control, automated tests, and artifact storage.
Key Challenges and Solutions:
Handling API Rate Limits:
Implemented retry logic with exponential backoff in the Lambda function.
Scalable Data Processing:
Used SQS to buffer and queue processing tasks for Lambda to handle high-volume data.
Optimizing Redshift COPY Command:
Ensured optimized performance by using manifest files and enabling data compression.
Deployment and Testing:
Leveraged Azure DevOps to run unit tests, package code, and deploy artifacts seamlessly.
