DESCRIPTION:Cloud object storage systems achieve scalability and fault isol
 ation by sharding metadata across independently managed domains. While mos
 t metadata operations naturally scale under this model\, rename remains a 
 fundamental challenge\, as it requires atomicity and strong consistency ac
 ross multiple metadata owners. This challenge is exacerbated when source a
 nd destination metadata reside in different shards\, operate without share
 d storage\, and cannot depend on global locks or global clocks.\n\nThis ta
 lk presents the design of a distributed rename protocol for cloud-scale ob
 ject storage systems\, enabling atomic renames across independent metadata
  domains. The protocol models rename as a recoverable\, multi-stage state 
 machine rather than a monolithic transaction. It relies on explicit transa
 ction tracking\, shard-local invariants\, and idempotent transitions\, all
 owing failures and concurrent operations to safely drive in-progress renam
 es toward completion or abort without centralized coordination.\n\nSpeaker
