Best For
Billion-scale vector workloads with the widest selection of ANN index types — HNSW, IVF, DiskANN, SCANN, GPU indexes
High-performance vector search with rich payload filtering — Rust-written, predictable latency, and a clean self-hosted path
Limitations
Self-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
No built-in embedding generation — bring your own embeddings; managed cloud is younger than Pinecone's; fewer turnkey RAG modules than Weaviate
