Feb 1, 2026February 2026 monthly summary for milvus-io/milvus focused on StorageV2 reliability, performance, and observability improvements. Delivered Storage V2 Global Enhancements including a unified StorageV2 filesystem cache (StorageV2FSCache) and conversion of the Key to api::Properties, enabling unified caching, metrics collection, improved filesystem instance management, and enhanced logging for retrieval operations. Extended StorageV2 to delta logs by integrating deltalog storage into segment manifests, replacing the FieldBinlog approach, and introducing a new transaction handling and compaction infrastructure to improve delta-log efficiency and organization. These changes establish a solid foundation for V2/V3 storage formats, improve observability, and drive more predictable performance across storage workflows.
