@Deprecated
public class JoinOperator
extends JoinOperatorBase<Record,Record,Record,JoinFunction>
implements RecordOperator

NOTE: The Record API is marked as deprecated. It is not being developed anymore and will be removed from the code at some point. See FLINK-1106 for more details. JoinOperator that applies a JoinFunction to each pair of records from both inputs that have matching keys.
