What to Do When Qdrant Indexing Is Too Slow Qdrant does NOT build HNSW indexes immediately. Small segments use brute-force until they exceed (default: 20 MB). Search during this window is slower by design, not a bug. - Understand the indexing optimizer Indexing optimizer Uploads/Ingestion Too Slow Use when: upload or upsert API calls are slow. Identify bottleneck: client-side (network, batching) vs server-side (CPU, disk I/O) For client-side, optimize batching and parallelism: - Use batch upserts (64-256 points per request) Points API - Use 2-4 parallel upload streams For server-side, optimiz…
