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

• 向量数据库：Qdrant is a specific vector database implementation
• Embedding：Qdrant stores embedding vectors
• RAG：Qdrant serves as the storage layer in RAG systems
• LangChain：LangChain can integrate with Qdrant as a vector store
