Best ForBillion-scale vector workloads with the widest selection of ANN index types — HNSW, IVF, DiskANN, SCANN, GPU indexes
Teams already on MongoDB who want vector search next to operational data — one driver, one query language, one backup story
LimitationsSelf-hosted deployment is operationally complex (depends on etcd, MinIO, Pulsar/Kafka); no first-party MCP server yet; managed offering is through Zilliz, not Milvus directly
Vector indexes are tied to Atlas (not self-hosted Community Server); search nodes add cost; index build times can be long for large collections
