> Currently SnapshotDiff process redundantly spills diff entries to PersistentLists 
> -delete-diff, -rename-diff, -create-diff, -modify-diff just to ensure order of snapshot diff which can be handled by SnapshotDiffReportTable keyPrefix.
> All we have to ensure with prefix:
> -delete-diff : jobid-1<index>
> -rename-diff:-jobid-2<index>
>  -create-diff:-jobid-3<index>
>  -modify-diff:jobid-4<index>
