Basic Information
- Type: Vector Database
- Source: RAG从入门到精通系列1：基础RAG
Definition
Qdrant is an open-source vector database written in Rust, designed for storing and searching high-dimensional embedding vectors with high performance.
Key Features
- Written in Rust: High performance and memory safety
- Vector Search: Supports similarity search with various metrics
- Open Source: Freely available for self-hosting
- RAG Integration: Commonly used as the vector store in RAG pipelines
Technical Details
- Implements various similarity comparison methods for embedding vectors
- Supports Top-k retrieval (returning k most similar results)
- Can store metadata alongside vectors
Related Concepts
