Change subject: IMPALA-12871: Added filtering capability for Calcite planner ...................................................................... IMPALA-12871: Added filtering capability for Calcite planner The Filter RelNode is now handled in the Calcite planner. The parsing and analysis is done by Calcite so there were no changes added to that portion. The ImpalaFilterRel class was created to handled the conversion of the Calcite LogicalFilter to create a filter condition within the Impala plan nodes. There is no explicit filter plan node in Impala. Instead, the filter condition attaches itself to an existing plan node. The filter condition gets passed into the children plan nodes through the ParentPlanRelContext. The ExprConjunctsConverter class is responsible for creating the filter Expr list that is used. The list contains separate AND conditions that are on the top level.
