Qdrant

QdrantSince 2025-03

Qdrant is an open-source, high-performance vector database and similarity search engine engineered in Rust for production AI systems, semantic search engines, and Retrieval-Augmented Generation (RAG) pipelines. It provides lightning-fast nearest-neighbor search with rich payload filtering and custom distance metrics. Unlike traditional databases adapted for vectors, Qdrant was designed from day one to handle high-dimensional neural embeddings at scale. Its Rust engine provides memory-efficient vector quantization (scalar, product, and binary), allowing engineering teams to search billions of vectors on cost-effective cloud hardware.

Qdrant features advanced hybrid search capabilities, combining dense vector embeddings with sparse BM25 keyword vectors and lexical filters in a single query execution plan. It includes native multi-tenant payload partitioning, dynamic indexing, and zero-downtime collection snapshots. With client SDKs for Python, TypeScript, Go, Rust, and Java, Qdrant powers mission-critical search infrastructures for thousands of modern AI applications.
