milvus-io/milvus
Milvus is a high-performance, cloud-native vector database built for scalable vector ANN search
Written in Go and C++, Milvus leverages hardware acceleration (CPU/GPU) and supports multiple vector index types (HNSW, IVF, SCANN, DiskANN) with quantization and memory-mapping for optimized search across different workloads. Its fully-distributed, Kubernetes-native architecture separates compute and storage layers, enabling independent scaling of query and data nodes, plus multi-tenancy isolation at database/collection/partition levels with hot/cold storage tiering. The SDK integrates seamlessly with Python (`pymilvus`) and supports hybrid search combining vector similarity with scalar metadata filtering and range queries.
