Feature Comparison

Vector Databases features side-by-side

Feature	LanceDB 14/18 features	Qdrant 16/18 features
Approximate nearest-neighbor index An HNSW, IVF or similar index serves top-k similarity queries in milliseconds over millions of vectors.	Yes	Yes
Filtered vector search on metadata Structured filters on payload fields applied inside the similarity search, not after it.	Yes	Yes
Hybrid keyword and vector search Sparse or keyword signals combined with dense embeddings in one ranked query.	Yes	Yes
Choice of similarity metrics Cosine, dot product and Euclidean distance selectable per collection or index.	Yes	Yes
Quantized index compression Scalar, product or binary quantization shrinks index memory with a tunable recall trade-off.	Yes	Yes
Multi-tenant namespaces per index Tenant data isolated inside one index so a per-customer query never scans other tenants.	No	Yes
Integrated embedding models Text or images embedded by a hosted model at write and query time, with no separate pipeline.	Yes	Yes
Built-in reranking stage A second-stage reranker model reorders the top candidates before results are returned.	Yes	Yes
Multiple named vectors per record Several vectors per record, such as text and image embeddings, searchable together.	Yes	Yes
Live upserts visible in seconds New or updated vectors become searchable within seconds while the index stays online.	Yes	Yes
Sharded vector collections Collections split across nodes for datasets beyond one machine's memory.	No	Yes
Replicated vector shards Each shard is copied to another node so queries keep answering through a node loss.	Yes	Yes
Disk-backed index beyond RAM Indexes served from SSD rather than memory so billions of vectors fit on modest hardware.	Yes	Yes
Collection snapshots and restore Point-in-time snapshots of a collection that can be restored or copied to another cluster.	Yes	Yes
Role-based keys per collection API keys or roles scoped to specific collections and to read or write operations.	No	Yes
Bulk import from Parquet files Vectors and metadata loaded in bulk from Parquet or JSON files in cloud storage.	Yes	No
Serverless usage-based pricing Billing by reads, writes and stored vectors, with no cluster to size in advance.	No	No
Open source self-hosted engine The engine's source is public and can be self-hosted without a commercial license.	Yes	Yes
