> I have made a simple test on a table with 11 partition levels and over 3 millions partitions, Thanks for helping to check. >the result shows a performance regression The performance regression you are referring to is (1.32 sec) vs (1.39 sec)? > https://github.com/apache/hive/pull/4831#discussion_r1530023612 This depends on the partition name. If most of your partition fields are the same, you really won't see too many different results, but if the partition fields are diverse, you can get some query performance improvements. -- This is an automated message from the Apache Git Service.
