High-performance vector similarity search engine
⭐ 35k+ stars
📜 Apache-2.0
🏷️ skill
Overview
High-performance vector similarity search engine
Pros
- ✓ Benchmarks show 2-3x faster filtered vector search vs Weaviate for high-cardinality payload filtering
- ✓ Written in Rust — delivers ~40% lower memory usage than comparable Python-based vector databases
- ✓ Sparse + dense hybrid search natively supported without additional components
Cons
- ✗ Qdrant Cloud free tier limited to 1GB storage and 1 collection — paid plans start at $25/month
- ✗ Smaller managed cloud ecosystem compared to Pinecone or Weaviate for enterprise compliance requirements
- ✗ Rust-based internals make custom extension development significantly harder than Python-native alternatives
Key Features
- ⚡2-3x Faster Filtered Search: Optimized vector search with high-cardinality payload filtering outperforms comparable solutions by 2-3x, enabling real-time queries on large filtered datasets.
- 🦀Rust-Powered Memory Efficiency: Native Rust implementation reduces memory consumption by ~40% compared to Python-based vector databases, lowering infrastructure costs at scale.
- 🔀Native Hybrid Search: Combine sparse and dense vector search natively in single queries without middleware or additional components, enabling BM25 + semantic fusion.
- 📊Arbitrary Payload Filtering: Filter vectors using complex conditions on stored metadata without separate indexes—supports structured data queries alongside similarity searches.
- 🚀Sub-millisecond Query Latency: Leverages Rust performance and optimized indexing to deliver sub-millisecond latencies for vector queries, critical for production search applications.
