> Eliminate file rename in insert-only compactor
> ----------------------------------------------

> Key: HIVE-22971
> URL: https://issues.apache.org/jira/browse/HIVE-22971
> Project: Hive
> Issue Type: Improvement
> Reporter: Karen Coppage
> Assignee: Karen Coppage
> Priority: Major
> Labels: ACID, compaction
> Attachments: HIVE-22971.01.patch, HIVE-22971.02.patch,

>
> File rename is expensive for object stores, so MM (insert-only) compaction
> should skip that step when committing and write directly to base_x_cZ or
> delta_x_y_cZ.
> This also fixes the issue that for MM QB compaction the temp tables were
> stored under the table directory, and these temp dirs were never cleaned up.
