Optimizing RAG at Scale: Chunking, Retrieval, and the Bayesian Search That Cut Latency 40%

📰 Dev.to AI

Learn how to optimize RAG at scale by implementing chunking, retrieval, and Bayesian search to reduce latency by 40% and achieve 95% recall@10

advanced Published 20 Jul 2026
Action Steps
  1. Implement chunking to split long documents into manageable pieces
  2. Use a retrieval pipeline with a tunable top-k parameter to improve recall
  3. Apply Bayesian search to optimize the retrieval process and reduce latency
  4. Test and evaluate the optimized RAG pipeline using metrics such as recall@10
  5. Configure and fine-tune the pipeline for specific use cases, such as legal contracts
Who Needs to Know This

This article is relevant for machine learning engineers and data scientists working on large-scale RAG implementations, particularly those dealing with long documents such as legal contracts. The techniques described can help improve the efficiency and accuracy of their RAG pipelines.

Key Insight

💡 Optimizing RAG at scale requires a measured and tunable approach to retrieval and search, rather than relying on default parameters and 'semantic search + hope'

Optimizing RAG at Scale: Chunking, Retrieval, and the Bayesian Search That Cut Latency 40% How we moved from "semantic search + hope" to a measured, tunable retrieval pipeline with 95% recall@10 The RAG Reality Check Everyone ships RAG the same way: chunk by 512 tokens, embed with text-embedding-3-small , top-k=5, stuff into context. It works for demos. Then you hit production: Legal contracts: 512 tokens splits clauses mid
