Volume Strip Lock: locking for volume +2. Bucket Strip Lock: locking for bucket +3. Key Strip Lock: Locking for key Review Comment: We have done bucketing of key spaces to "volume" --> "bucket", so based on current operating model in ozone, so, we do not need lock entire key space. - for key operation, generally volume lock is not required, just `bucket Read lock`, and then the related key. - for bucket operation, volume read lock Currently we do not have operation to lock entire tree structure, and should be avoided. -- This is an automated message from the Apache Git Service.
