IMPALA-15416: Fix compound predicate push-down test for Calcite
TestIcebergTable.test_compound_predicate_push_down failed in the
Calcite planner build with an unexpected NumRowGroups value (10
instead of 12) for the query with the following predicate:
not (col_bi + 1 != 123 or col_db = 2.71822 or col_i = -1)
The legacy planner cannot push this predicate down to Iceberg, as
'col_bi + 1 != 123' cannot be converted to an Iceberg expression.
Calcite pushes the NOT into the OR, so the predicates become
separate conjuncts, and 'NOT col_db = 2.71822' is pushed down to
Iceberg. Since the Iceberg 1.11 upgrade (IMPALA-15330) Iceberg
skips data files for NOT_EQ predicates when the lower and upper
bounds are equal to the literal, which is true for two data files.
This patch adds a CALCITE_PLANNER_RUNTIME_PROFILE section for the
query that expects 10 row groups.
Testing:
* ran test_compound_predicate_push_down with both planners
