[jira] [Created] (CALCITE-3309) Refactor generatePredicate method from EnumerableNestedLoopJoin/EnumerableHashJoin/EnumerableBatchNestedLoopJoin into a single location

Ruben Quesada Lopez created CALCITE-3309:
--------------------------------------------

             Summary: Refactor generatePredicate method from EnumerableNestedLoopJoin/EnumerableHashJoin/EnumerableBatchNestedLoopJoin into a single location
                 Key: CALCITE-3309
                 URL: https://issues.apache.org/jira/browse/CALCITE-3309
             Project: Calcite
          Issue Type: Improvement
            Reporter: Ruben Quesada Lopez
            Assignee: Ruben Quesada Lopez
             Fix For: 1.21.0


The method {{EnumerableNestedLoopJoin#predicate}} (that generates a Predicate Expression based on a RexNode condition) has been copied pasted as {{EnumerableBatchNestedLoopJoin#generatePredicate}} due to CALCITE-2979, and {{EnumerableHashJoin#generatePredicate}} due to CALCITE-2973.
The goal of this ticket is to refactor that method into a single location (e.g. EnumUtils) where it can be accessible by all 3 Enumerable Joins.
