Milvus·medium signal

Milvus published v3.0 release candidate in May 2026, introducing data lake/warehouse-based data processing as the architectural foundation. New capabilities include External Collections, Snapshot support, Storage V3 engine, lake ecosystem integrations, nullable vector fields, entity-level TTL, MinHash functions for server-side signatures, and search-with-embedding-lists. The 3.0 RC represents a major architectural shift for the vector database (44K+ GitHub stars) from pure vector search toward hybrid data lake capabilities.
