hudi-bot opened a new issue, #15766:
URL: https://github.com/apache/hudi/issues/15766

   As of now, our restore is triggering N rollbacks in reverse chronological 
order. 
   
   for MOR table, we need to re-think this, since our rollbacks are log 
appends, even if we want to restore to a delta commit just before last 
compaction, instead of directly cleaning up the lastest file slice, we are 
triggering rollbacks of N delta commits and finally cleaning up the entire file 
slice when the compaction instant is being rolledback. 
   
    
   
   we can optimize things better here for MOR table. we just need to re-think 
restore from scratch w/o the need for going thru N rollbacks.
