### Change Logs
For MOR Table, restoring to a very old delta commit is very time consuming.
since internally, we do rollback of 1 commit at a time. This standalone tool
takes a stab at improving the performance of restore. You can choose a delta
commit just before a compaction commit, and this tool will directly delete
files for newer file slices after the delta commit chosen.
Caution:
Metadata has to be disbaled.
And this tool takesn unconventional route of not going via rollback. This
tool directly lists the files and deletes them and also deleted the timeline
files if necessary.
### Impact
