Change subject: IMPALA-13465: Trace TupleId further to reduce Agg cardinality ...................................................................... Patch Set 26: (2 comments) http://gerrit.cloudera.org:8080/#/c/21955/26/testdata/workloads/functional-planner/queries/PlannerTest/agg-node-max-mem-estimate.test File testdata/workloads/functional-planner/queries/PlannerTest/agg-node-max-mem-estimate.test: http://gerrit.cloudera.org:8080/#/c/21955/26/testdata/workloads/functional-planner/queries/PlannerTest/agg-node-max-mem-estimate.test@a1157 PS26, Line 1157: Could you comment on why this test was removed ? It was introduced in IMPALA-13405 and I thought it was useful for the memory estimate of Aggs in a nested view (based on the cardinality estimate). I suppose this scenario is covered elsewhere ? http://gerrit.cloudera.org:8080/#/c/21955/26/testdata/workloads/functional-planner/queries/PlannerTest/tpcds_cpu_cost/tpcds-q31.test File testdata/workloads/functional-planner/queries/PlannerTest/tpcds_cpu_cost/tpcds-q31.test: http://gerrit.cloudera.org:8080/#/c/21955/26/testdata/workloads/functional-planner/queries/PlannerTest/tpcds_cpu_cost/tpcds-q31.test@83 PS26, Line 83: | | tuple-ids=28 row-size=50B cardinality=1.43M cost=299319961 Any idea why the cost of this operator did not change even though the cardinality went up by 3 orders of magnitude.
