Key criteria to evaluate when comparing Vector Databases solutions:
Qdrant is a high-performance open-source vector database written in Rust, optimized for speed and reliability. It supports advanced filtering with payload indexes, quantization for memory efficiency, and distributed deployments for horizontal scaling. Qdrant offers a managed cloud service and is popular with teams that need production-grade vector search with fine-grained control over indexing and query parameters.
Redis provides vector similarity search as part of its in-memory data platform. Redis Vector Search enables real-time semantic search with sub-millisecond latency, supporting HNSW and FLAT indexing algorithms. Ideal for applications requiring both traditional caching and vector search in a single data layer.
Purpose-built databases for storing, indexing, and querying high-dimensional vector embeddings used in semantic search, RAG, and recommendation systems.
Browse all Vector Databases tools →A vector database stores high-dimensional numerical representations (embeddings) of data like text, images, or audio, and enables fast similarity search across millions or billions of vectors using approximate nearest neighbor algorithms.
For small to medium datasets (under 10 million vectors), pgvector in PostgreSQL works well and avoids adding another service. For larger datasets or when you need advanced features like hybrid search and real-time indexing, a dedicated vector database is recommended.
Match the embedding model to your use case. For general text search, models like OpenAI text-embedding-3 or Cohere embed-v3 work well. For domain-specific applications, consider fine-tuned models. Always benchmark with your actual data.
