Change subject: IMPALA-7996: Optimize constant-false outer joins ...................................................................... Patch Set 3: With regards to my previous comment: Again, my join algorithm knowledge is lacking a bit here, but I wonder how a full outer join is handled in terms of a "build" and "probe" side. Maybe a partitioned hash join is needed for that? But I would still think it could be avoided for left outer join and right outer join. -- To view, visit http://gerrit.cloudera.org:8080/24597 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I6505825fc958720eec12e13d546661834f221b80 Gerrit-Change-Number: 24597 Gerrit-PatchSet: 3 Gerrit-Owner: Aleksandr Efimov <[email protected]> Gerrit-Reviewer: Aleksandr Efimov <[email protected]> Gerrit-Reviewer: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Michael Smith <[email protected]> Gerrit-Reviewer: Paul Rogers <[email protected]> Gerrit-Reviewer: Steve Carlin <[email protected]> Gerrit-Reviewer: Yifan Zhang <[email protected]> Gerrit-Comment-Date: Wed, 29 Jul 2026 17:31:32 +0000 Gerrit-HasComments: No
