>
> Operations like Clean, Compaction are retried after failures with the same
> instant time. If the previous run of the operation successfully committed to
> the MDT but failed to commit to the dataset, then the operation will be
> retried later with the same instantTime causing duplicate updates applied to
> MDT.
> Currently, we simply delete the completed deltacommit without rolling back
> the deltacommit.
> To handle this, we detect a replay of operation and rollback any changes from
> that operation in MDT.
