The dynamic filter from HashJoinExec was previously gated to Inner joins only. Left and LeftSemi joins have the same probe-side filtering semantics. PR #20192 added a fine-grained lr_is_preserved allowing parent filters to pass through non-inner joins. This PR relaxes the gate to also allow Left and LeftSemi joins, which are now trivially supported. ## Which issue does this PR close? This PR makes progress on #16973 ## Rationale for this change The self-generated dynamic filter in HashJoinExec filters the probe side using build-side values. For Left and LeftSemi joins, the right-hand probe side has the same filtering semantics as Inner. Relaxing the gate to take advantage of this optimization for Left and LeftSemi joins. ## Are these changes tested? Yes. ## Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
