Qdrant

What is Qdrant?

Qdrant is a high-performance, open-source vector database specifically designed for handling high-dimensional vector data and similarity search operations. Built entirely in Rust, it provides exceptional speed, reliability, and scalability for modern machine learning and data science applications. The platform excels at storing, indexing, and querying billions of vectors while maintaining low latency and high accuracy. Qdrant supports various distance metrics including cosine, dot product, and Euclidean distance, and features advanced filtering capabilities that enable hybrid search combining semantic relevance with structured metadata conditions. Its cloud-native architecture ensures seamless scaling and zero-downtime upgrades.

Key Features

• High-Performance Vector Search

  Built-in HNSW indexing algorithm delivers fast and accurate nearest neighbor search on dense vector data with support for multiple distance metrics and low-latency queries on large datasets.

• Advanced Filtering and Hybrid Search

  Combines vector similarity search with structured metadata filters, enabling context-aware results through numeric, text, and tag-based filtering alongside semantic ranking.

• Real-Time Data Operations

  Supports immediate searchability after vector insertion with consistent performance for frequent insert, update, and delete operations in production environments.

• Flexible Deployment Options

  Runs as standalone binary or in Docker/Kubernetes with REST and gRPC APIs, offering SDKs for Python, JavaScript, Go, and Rust for seamless integration.

• Storage Optimization

  Memory-mapped file access with on-disk persistence, built-in compression options, and efficient resource usage for both high-load and constrained environments.
