---------------------------------------
[~swamirishi] this is an old ticket and I believe this is going to be taken
care of by HDDS-12562?
> [Snapshot] Performance impact for key & directory deleting service
> ------------------------------------------------------------------
>
> Key: HDDS-8599
> URL: https://issues.apache.org/jira/browse/HDDS-8599
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Sumit Agrawal
> Priority: Critical
>
> Scenario:
> # Huge number of keys and directories are created in bucket (FSO)
> # Snapshot is taken for the bucket
> # Recursive delete of keys and directory
> # keys and directories are added to deletedTable and deletedDirectoryTable
> KeyDeletingService:
> * iterator all keys in deleted Table
> ** if keys are present in snapshot, its skipped
> ** else added for blockGroupList for deletion
> DirectoryDeletingService:
> * iterator all directory in deleted directory table
> ** if directory is present in snapshot, its skipped
> ** else perform further action for deletion
> So if number of keys and directory are huge, it will keep iterating always to
> get candidate keys/directory for deletion.
