VEARCH
Cloud-native vector database for AI-native similarity search
ABOUT
Running vector search at scale requires a database that can store, index, and query billions of embeddings with low latency, while also supporting real-time updates, hybrid search (vector + scalar filters), and horizontal scaling. Most vector search libraries are single-node tools, and cloud-managed solutions can be expensive at scale. Vearch is a distributed, cloud-native vector database built for Kubernetes. It partitions and replicates data across shards automatically, supports IVF_PQ and HNSW indexing, and provides RESTful and gRPC APIs. It handles both dense embeddings and scalar attribute filtering, making it suitable for production RAG pipelines and recommendation systems that need to scale without a per-query high cost.
