方法详细资料

process

<OUT> GlobalStream.ProcessConfigurableAndGlobalStream<OUT> process(OneInputStreamProcessFunction<T,OUT> processFunction)

Apply an operation to this GlobalStream.

参数:

processFunction - to perform operation.

返回:

new stream with this operation.

process

<OUT1,OUT2> GlobalStream.TwoGlobalStreams<OUT1,OUT2> process(TwoOutputStreamProcessFunction<T,OUT1,OUT2> processFunction)

Apply a two output operation to this GlobalStream.

参数:

processFunction - to perform two output operation.

返回:

new stream with this operation.

connectAndProcess

<T_OTHER,OUT> GlobalStream.ProcessConfigurableAndGlobalStream<OUT> connectAndProcess(GlobalStream<T_OTHER> other,
                                                                                     TwoInputNonBroadcastStreamProcessFunction<T,T_OTHER,OUT> processFunction)

Apply a two input operation to this and other GlobalStream.

参数:

other - GlobalStream to perform operation with two input.

processFunction - to perform operation.

返回:

new stream with this operation.

keyBy

<K> KeyedPartitionStream<K,T> keyBy(org.apache.flink.api.java.functions.KeySelector<T,K> keySelector)

Transform this stream to a KeyedPartitionStream.

参数:

keySelector - to decide how to map data to partition.

返回:

the transformed stream partitioned by key.

shuffle

NonKeyedPartitionStream<T> shuffle()

Transform this stream to a new NonKeyedPartitionStream, data will be shuffled between these two streams.

返回:

the transformed stream after shuffle.

broadcast

BroadcastStream<T> broadcast()

Transform this stream to a new BroadcastStream.

返回:

the transformed BroadcastStream.

toSink

ProcessConfigurable<?> toSink(org.apache.flink.api.connector.dsv2.Sink<T> sink)
