Strengths
  • + Single-stage metadata filtering during HNSW traversal rather than pre/post-filtering
  • + Quantization options (scalar, product, binary) cut memory footprint substantially
  • + Native hybrid search with dense, sparse, and late-interaction reranking
  • + Rust implementation with REST/gRPC APIs and official Python/JS clients
  • + Object-storage-backed; cheap at rest
  • + Hybrid vector + BM25 search
  • + Per-namespace isolation
Tradeoffs
  • − No built-in embedding modules historically; you manage vectorization yourself (cloud inference is newer)
  • − Distributed mode requires manual sharding and replication decisions compared to fully elastic systems
  • − Less natural fit than pgvector for teams wanting vectors inside an existing Postgres stack
  • − Newer player; smaller ecosystem than Pinecone
