Infinity (InfiniFlow) vs Milvus

Infinity (InfiniFlow): AI-native C++ database for hybrid search over dense, sparse, multi-vector (tensor) and full text. Milvus: Cloud-native, distributed open-source vector database built for billions of vectors.

key differences

  • Milvus is built for larger datasets (Multi-PB) than Infinity (InfiniFlow) (≤ 10 TB).
  • Horizontal scaling is none in Infinity (InfiniFlow) and native in Milvus.
  • Transactions: Infinity (InfiniFlow) offers limited ACID; Milvus offers none.
  • Only Milvus has json, change data capture, ttl / expiry, role-based access, online schema changes.
