Five Essential Techniques for Production GraphRAG

Five essential optimization techniques: 1) Semantic-Aware Chunking — Use 512 tokens with 64-token overlap, improving entity extraction quality by 40%. 2) Parallel Entity Extraction — Process chunks in parallel with 8-16 concurrent requests for 5x speedup. 3) Batch Database Operations — Use batch inserts of 100-500 rows, reducing write time by 90%. 4) Lock Resolution Strategy — Implement retry logic with exponential backoff, eliminating 15-30% deadlock rate. 5) LLM Request Batching — Group extraction requests, reducing API costs by 60%. Results: Ingestion dropped from 56 hours to 4.1 hours.
