IMPALA-15135: Calcite planner: added support for Kudu tables
This commit enables the Calcite planner to support queries on
Kudu tables. Highlights include:
- The Kudu tables can have an auto_incrementing_id column that
does not show up when a "select *" is done on the query. Special
logic has been added to support this. If the user expliclity selects
the auto_incrementing_id column, the query will fall back to the
original planner (IMPALA-15136 has been filed for this).
- A small refactor was done for PrunedPartitionHelper to handle
Kudu tables because it does not support code in the HdfsPartitionPruner.
- A small refactor was done in CalciteDb to handle FeKuduTable
- IMPALA-15134 has been filed on an issue where the cardinality on
the KuduScan table is different from the original planner.
- Added some code in the test framework to handle the section
CALCITE_PLANNER_RUNTIME_PROFILE for when a table format is specified.
