Mithun Radhakrishnan commented on HIVE-8313: -------------------------------------------- FWIW, the test failure doesn't look related to this change. > Optimize evaluation for ExprNodeConstantEvaluator and ExprNodeNullEvaluator > --------------------------------------------------------------------------- > > Key: HIVE-8313 > URL: https://issues.apache.org/jira/browse/HIVE-8313 > Project: Hive > Issue Type: Bug > Components: Query Processor > Affects Versions: 0.12.0, 0.13.0, 0.14.0 > Reporter: Mithun Radhakrishnan > Assignee: Mithun Radhakrishnan > Attachments: HIVE-8313.1.patch, HIVE-8313.2.patch > > > Consider the following query: > {code:sql} > SELECT foo, bar, goo, id > FROM myTable > WHERE id IN ( 'A', 'B', 'C', 'D', ... , 'ZZZZZZ' ); > {code} > One finds that when the IN clause has several thousand elements (and the > table has several million rows), the query above takes orders-of-magnitude > longer to run on Hive 0.12 than say Hive 0.10. > I have a possibly incomplete fix. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
