Change subject: IMPALA-13465: Trace TupleId further to reduce Agg cardinality ...................................................................... Patch Set 11: (1 comment) http://gerrit.cloudera.org:8080/#/c/21955/8/testdata/workloads/functional-planner/queries/PlannerTest/aggregation.test File testdata/workloads/functional-planner/queries/PlannerTest/aggregation.test: http://gerrit.cloudera.org:8080/#/c/21955/8/testdata/workloads/functional-planner/queries/PlannerTest/aggregation.test@1328 PS8, Line 1328: | row-size=16B cardinality=9.1 > Use num rows of table before conjunct and limit for capping.
