@InvisibleProgrammer , @SourabhBadhya, any measurements on a query performance change after the "inner select"? what is the effect of the optimization? Are we sure it won't cause this query to run forever (massive TXN_COMPONENTS) That is the critical area and we haven't done any perf tests? I'll certainly exclude it from 4.0 release and don't recommend backporting it see example https://github.com/apache/hive/pull/4744 -- This is an automated message from the Apache Git Service.
