toString: StringJoinStateWatermarkPredicates — Watermark Predicates for State Removal
JoinStateWatermarkPredicates contains watermark predicates for state removal of the children of a StreamingSymmetricHashJoinExec physical operator:
-
JoinStateWatermarkPredicate for the left-hand side of a join (default:
None) -
JoinStateWatermarkPredicate for the right-hand side of a join (default:
None)
JoinStateWatermarkPredicates is created for the following:
-
StreamingSymmetricHashJoinExec physical operator is created (with the optional properties undefined, including JoinStateWatermarkPredicates)
-
StreamingSymmetricHashJoinHelperutility is requested for one (forIncrementalExecutionfor the state preparation rule to optimize and specify the execution-specific configuration for a query plan with StreamingSymmetricHashJoinExec physical operators)
