Enterprise ETL Data Pipelines & OpenSearch RAG

High-Throughput Vector Ingestion & Hybrid Search

Power enterprise RAG applications with real-time neural data lakes. We engineer high-throughput data pipelines using AWS Glue PySpark jobs, S3 Iceberg, serverless Lambda embedders, and OpenSearch hybrid vector search indices.

High-Scale Vector RAG & Streaming Data Pipeline

Production-tested execution flow designed for multi-region reliability and security.

01

Raw Event Ingestion

Streams document updates and database change logs via Kinesis to S3.

02

AWS Glue PySpark Cleaning

Executes serverless PySpark ETL to chunk text and format into Snappy Parquet.

03

Lambda Serverless Embedding

Generates dense vector embeddings using foundation embedding models.

04

OpenSearch k-NN Hybrid Index

Updates BM25 lexical + dense k-NN vector search indices for sub-50ms RAG queries.

Key Engineering Capabilities

Serverless AWS Glue PySpark ETL

Scales automatically to process millions of unstructured enterprise documents and log streams.

OpenSearch Hybrid Lexical + Vector Indexing

Combines traditional BM25 keyword search with dense k-NN vector embeddings for high retrieval accuracy.

Real-Time Streaming Pipeline Architecture

Ingests document edits via AWS Kinesis and Lambda embedders so RAG stores stay continuously updated.

S3 Iceberg Data Lake Optimization

Stores raw and processed corpora in open columnar formats with compression and temporal versioning.

Frequently Asked Questions

Why combine BM25 keyword search with vector embeddings in OpenSearch?

Pure vector search can miss exact alphanumeric strings like part numbers or customer IDs. Hybrid search merges BM25 keyword precision with semantic vector context.

How does AWS Glue PySpark scale for large document stores?

AWS Glue runs PySpark jobs serverlessly, automatically allocating worker nodes based on dataset volume to process terabytes of data quickly.
