> New Sort SEMI/ANTI Join Transpose optimization
> ----------------------------------------------
>
> Key: CALCITE-4475
> URL: https://issues.apache.org/jira/browse/CALCITE-4475
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Reporter: Ruben Q L
> Priority: Major
>
> If I am not mistaken, the optimization that is currently applied by
> {{SortJoinTransposeRule}} for LEFT and RIGHT joins could also by applied to
> SEMI / ANTI joins (it would be very similar to the current LEFT join
> optimization).
> It is proposed to either improve this rule to cover SEMI / ANTI joins or
> create a new dedicated rule for this matter.
