Ruben Q L updated CALCITE-4621:
-------------------------------
Description:
Credits to [~thomas.rebele] for discovering the issue.
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.
