Wellington Chevreuil updated HBASE-26187:
-----------------------------------------
Status: Patch Available (was: Open)
> Write straight into the store directory when Splitting and Merging
> ------------------------------------------------------------------
>
> Key: HBASE-26187
> URL: https://issues.apache.org/jira/browse/HBASE-26187
> Project: HBase
> Issue Type: Improvement
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Major
>
> As discussed with [~zhangduo] on HBASE-26079, we think there's no actual need
> for Splits/Merges to make use of temp directories, because the split/merge
> region files would not be loaded until the new regions are ready to open,
> meaning the split/merge operation has completed. This would then avoid the
> need for a FS rename at the end of split/merge operation.
