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). -- This message was sent by Atlassian Jira (v8.3.4#803005)
