Month: 2026-01 – Mooncake repository (kvcache-ai/Mooncake) delivered a strategic API enhancement to improve operational flexibility and reduce friction in object lifecycle management. Key feature: Add a force parameter to the Remove API to bypass lease and replication checks, enabling immediate removal of objects even when leases exist. This supports urgent cleanup scenarios and automation workflows, aligning with reliability and agility goals. The change required updates across API, client interfaces, and service implementations, and was implemented with a focus on backward-compatible surface and minimal risk. Commit reference: 47633c4661f40cf0876d796a45322fe2cb9a1f6b (\"[Store] Add force remove option for remove api (#1425)\").
