--------------------------------------------
Summary: 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
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.
