Qdrant
Qdrant is the vector database you choose when you care about search quality and filtering performance. Written in Rust, it delivers consistent low-latency vector search with payload filtering that most other vector databases can't match.
What it is
Qdrant is a vector similarity search engine that stores vectors alongside payload data (metadata) and allows filtering on that metadata before or during the search. It's designed for production RAG applications where you need to search across millions of vectors with complex business logic filters.
Performance you'll see
| Hardware | Vectors | Latency (p99) | Recall |
|---|---|---|---|
| Single server (64GB RAM) | 10M vectors at 768d | under 50ms | 0.99 |
| Single server (128GB RAM) | 50M vectors at 768d | under 100ms | 0.98 |
| 3-node cluster | 500M vectors at 768d | under 200ms | 0.98 |
How it stacks up
| Qdrant | Chroma | Milvus | Weaviate | |
|---|---|---|---|---|
| Written in | Rust | Python | Go/C++ | Go |
| Filtering | Best | Good | Great | Great |
| Quantization | Yes (scalar, product, binary) | No | Yes | Yes |
| Distributed | Yes | No | Best | Yes |
| Ease of setup | Medium | Easy | Hard | Medium |
| Best for | Production RAG | Prototyping | Billion-scale | All-in-one |
