Qdrant: Overview of a High-Performance Vector Search Engine

Qdrant is a "vector similarity search engine" and vector database that provides production-oriented features for embedding-based search, recommendation, and matching applications. It supports high-performance similarity search over stored points—vectors plus JSON payloads—and is designed to satisfy real-service requirements through filtering, faceting, hybrid search combining dense and sparse vectors, quantization, and distributed deployment. According to the repository description and documentation, Qdrant is written in Rust to target performance and reliability under heavy load. It also offers Qdrant Cloud as a managed service and Qdrant Edge as a lightweight version embedded within an application. The source repository provides a Quick Start, APIs through OpenAPI, a gRPC interface, a Web UI, and client libraries for Python, Go, JavaScript, Rust, and other languages.
