> Key: HIVE-27160
> URL: https://issues.apache.org/jira/browse/HIVE-27160
> Project: Hive
> Issue Type: Task
> Reporter: Denys Kuzmenko
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently, in MOR mode, Hive creates "positional delete" files during
> deletes. With "Delete from ", the entire dataset in the table or partition is
> written as a "positional delete" file.
> During the read operation, all these files are read again causing huge delay.
> Proposal: apply "truncate" optimization in case of "delete *".
