A serverless pipeline that processes documents in parallel and generates vector embeddings for similarity search using AWS Step Functions, Lambda, and Amazon Bedrock
This sample project demonstrates how to build a production-ready document vectorization pipeline using AWS Step Functions to orchestrate parallel processing of documents. The pipeline intelligently handles different document formats and processes them in parallel chunks for optimal performance.
The state machine routes text, PDF, and Word documents to specialized Lambda functions for content extraction, then leverages parallel processing to generate vector embeddings using Amazon Bedrock's Titan models. All vectors are stored in PostgreSQL with pgvector extension for efficient similarity search.
Key features include automatic document type detection, parallel chunk processing, serverless scaling, and comprehensive error handling - making it suitable for high-throughput production workloads.

Deploy
Deploy the complete pipeline with database initialization: <code>./deploy-with-db-init.sh --region us-east-1</code>Or deploy infrastructure only: <code>sam build && sam deploy --guided</code>Then initialize the database: <code>./deploy-db-init.sh --region us-east-1</code>
Testing
See the GitHub repo for detailed testing instructions.
