Concurrent Update Behavior IBM Cloud Object Storage (COS) provides strong read-after-write consistency for the creation of new objects. However, updates to existing objects follow an eventual consistency model. In high-concurrency scenarios where multiple PUT requests target the same object key, the system employs a "Last-Writer-Wins" resolution strategy. Cr
Context IBM Cloud Object Storage (COS) supports multi-region and cross-region bucket configurations where object versions are time-stamped by the system clock of the receiving endpoint. In deployments spanning multiple regions, each data center operates on its own clock, introducing potential drift of tens to hundreds of milliseconds. Uncertainty The eventua
