Method Details

join

public static <IN1,
IN2,
OUT>
TwoInputNonBroadcastStreamProcessFunction<IN1,IN2,OUT> join(JoinFunction<IN1,IN2,OUT> joinFunction)

Wrap the JoinFunction and INNER JoinType within a ProcessFunction to perform the Join operation. Note that the wrapped process function should only be used with KeyedStream.

join

public static <IN1,
IN2,
OUT>
TwoInputNonBroadcastStreamProcessFunction<IN1,IN2,OUT> join(JoinFunction<IN1,IN2,OUT> joinFunction,
 JoinType joinType)

Wrap the JoinFunction and JoinType within a ProcessFunction to perform the Join operation. Note that the wrapped process function should only be used with KeyedStream.

join

public static <KEY,
T1,
T2,
OUT>
NonKeyedPartitionStream<OUT> join(KeyedPartitionStream<KEY,T1> leftStream,
 KeyedPartitionStream<KEY,T2> rightStream,
 JoinFunction<T1,T2,OUT> joinFunction)

Inner join two KeyedPartitionStream.

join

public static <KEY,
T1,
T2,
OUT>
NonKeyedPartitionStream<OUT> join(KeyedPartitionStream<KEY,T1> leftStream,
 KeyedPartitionStream<KEY,T2> rightStream,
 JoinFunction<T1,T2,OUT> joinFunction,
 JoinType joinType)

Join two KeyedPartitionStream with the type of JoinType.

join

public static <KEY,
T1,
T2,
OUT>
NonKeyedPartitionStream<OUT> join(NonKeyedPartitionStream<T1> leftStream,
 org.apache.flink.api.java.functions.KeySelector<T1,KEY> leftKeySelector,
 NonKeyedPartitionStream<T2> rightStream,
 org.apache.flink.api.java.functions.KeySelector<T2,KEY> rightKeySelector,
 JoinFunction<T1,T2,OUT> joinFunction)

Inner join two NonKeyedPartitionStream. The two streams will be redistributed by KeySelector respectively.
