Qdrant
Also known as: Qdrant / クァドラント
A high-performance open-source vector database written in Rust. It features HNSW indexing, payload filtering, and quantization-based fast ANN search, available self-hosted or as Qdrant Cloud.
Overview
Qdrant's Rust implementation delivers excellent memory efficiency and throughput. Its payload filtering enables filtered ANN search that combines vector similarity with metadata conditions.
RAG Adoption
Qdrant has integration documentation for LangChain, LlamaIndex, and the Anthropic SDK, making it a practical choice for internal knowledge RAG systems. See building RAG knowledge with OpenClaw.
