-----------------------------------
Summary: decorrelateRel method should return when meeting
SEMI/ANTI join in RelDecorrelator
Key: CALCITE-3169
URL: https://issues.apache.org/jira/browse/CALCITE-3169
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.20.0
Reporter: godfrey he
Fix For: 1.21.0
{code:java}
/**
* Rewrite LogicalJoin.
*
* @param rel Join
*/
public Frame decorrelateRel(LogicalJoin rel) {
// For SEMI/ANTI join decorrelate it's input directly,
// because the correlate variables can only be propagated from
// the left side, which is not supported yet.
if (!rel.getJoinType().projectsRight()) {
decorrelateRel((RelNode) rel);
}
...
{code}
`return` is missing before `decorrelateRel((RelNode) rel);`
