Summary: Optimise file move in CTAS
Key: HIVE-23140
URL: https://issues.apache.org/jira/browse/HIVE-23140
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Reporter: Rajesh Balamohan
Assignee: Rajesh Balamohan
Attachments: HIVE-23140.1.patch
FileSinkOperator can be optimized to run file move operation (/_tmp.-ext -->
/-ext-10002) in parallel fashion. Currently it invokes
{{Utilities.moveSpecifiedFileStatus}} and renames in sequential mode causing
delays in cloud storage. FS rename can be used (S3A internally has parallel
rename operation).
