Vineet Garg created HIVE-22074: ---------------------------------- Summary: Slow compilation due to IN to OR transformation Key: HIVE-22074 URL: https://issues.apache.org/jira/browse/HIVE-22074 Project: Hive Issue Type: Improvement Components: Logical Optimizer Reporter: Vineet Garg Assignee: Vineet Garg
Currently Hive transform IN expressions to OR to apply various CBO rules. This incur significant performance hit if IN consist of large number of expressions. It is better to not transform IN expressions to OR in such cases because overall benefit of various optimizations/transformations is unrealized due to the compilation overhead -- This message was sent by Atlassian JIRA (v7.6.14#76016)
