Change subject: IMPALA-12183: Fix cardinality clamping across aggregation phases ...................................................................... Patch Set 5: (1 comment) http://gerrit.cloudera.org:8080/#/c/20009/5/testdata/workloads/functional-planner/queries/PlannerTest/tpcds/tpcds-q67.test File testdata/workloads/functional-planner/queries/PlannerTest/tpcds/tpcds-q67.test: http://gerrit.cloudera.org:8080/#/c/20009/5/testdata/workloads/functional-planner/queries/PlannerTest/tpcds/tpcds-q67.test@512 PS5, Line 512: mem This is a significant reduction in memory estimate. Is this because the cardinality is capped to the input cardinality of 07:AGGREGATE? But, I don't see that reflected in the cardinality estimate on the plan. I was hoping that would also get updated. -- To view, visit http://gerrit.cloudera.org:8080/20009 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I1d414fe56b027f887c7f901d8a6799a388b16b95 Gerrit-Change-Number: 20009 Gerrit-PatchSet: 5 Gerrit-Owner: Riza Suminto <[email protected]> Gerrit-Reviewer: Abhishek Rawat <[email protected]> Gerrit-Reviewer: Aman Sinha <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Kurt Deschler <[email protected]> Gerrit-Reviewer: Riza Suminto <[email protected]> Gerrit-Comment-Date: Fri, 09 Jun 2023 23:39:00 +0000 Gerrit-HasComments: Yes
