Ruben Q L created CALCITE-4621: ---------------------------------- Summary: SemiJoinRule throws AssertionError on ANTI join Key: CALCITE-4621 URL: https://issues.apache.org/jira/browse/CALCITE-4621 Project: Calcite Issue Type: Bug Components: core Affects Versions: 1.26.0 Reporter: Ruben Q L Assignee: Ruben Q L Fix For: 1.27.0
When SemiJoinRule (both {{CoreRules.JOIN_TO_SEMI_JOIN}} and {{CoreRules.PROJECT_TO_SEMI_JOIN}}) matches an ANTI join, it fails with the following error: {noformat} java.lang.AssertionError: ANTI at org.apache.calcite.rel.rules.SemiJoinRule.perform(SemiJoinRule.java:122) ... {noformat} The problem is that the rule config only forbids RIGHT and FULL joins, and lets ANTI go through. Later when the rule is actually executed, joins with type ANTI cannot be handled, hence the {{AssertionError}}. The rule config must be adapted to forbid also ANTI joins. -- This message was sent by Atlassian Jira (v8.3.4#803005)
