Ruben Q L created CALCITE-4042: ---------------------------------- Summary: JoinCommuteRule should not match SEMI / ANTI join Key: CALCITE-4042 URL: https://issues.apache.org/jira/browse/CALCITE-4042 Project: Calcite Issue Type: Bug Components: core Affects Versions: 1.23.0 Reporter: Ruben Q L Assignee: Ruben Q L Fix For: 1.24.0
JoinCommuteRule should not match SEMI / ANTI join, because these types cannot be swapped. This is a minor issue, because the "default" JoinCommuteRule.INSTANCE matches only INNER joins. However, there is another version of the rule (JoinCommuteRule.SWAP_OUTER, currently only used in a few unit tests), to match also outer joins, which could potentially match a SEMI / ANTI join. -- This message was sent by Atlassian Jira (v8.3.4#803005)
