> Fix the bug in checking aggregate input references in AggregateJoinRemoveRule
> -----------------------------------------------------------------------------
>
> Key: CALCITE-4287
> URL: https://issues.apache.org/jira/browse/CALCITE-4287
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Liya Fan
> Assignee: Liya Fan
> Priority: Major
>
> In {{AggregateJoinRemoveRule#onMatch}}, the logic of checking if the
> aggregate references any columns from the other side is incorrect.
> For example, given an aggregate on a left join, the logic checks if the
> aggregate references any columns from the right side. If the aggregate
> happens to references the last column of the left input, the current
> implementation will make a wrong decision to skip the rule match.
> This will miss opportunities of simplifying the plan.
