类 PartitioningEvent

java.lang.Object

org.apache.flink.cdc.runtime.partitioning.PartitioningEvent

所有已实现的接口:

org.apache.flink.cdc.common.event.Event

@Internal
public class PartitioningEvent
extends Object
implements org.apache.flink.cdc.common.event.Event

A wrapper around Event, which contains the target partition number and will be used in EventPartitioner.

方法详细资料

ofRegular

public static PartitioningEvent ofRegular(org.apache.flink.cdc.common.event.Event payload,
                                          int targetPartition)

For partitioning events with regular topology, source partition information is not necessary.

ofDistributed

public static PartitioningEvent ofDistributed(org.apache.flink.cdc.common.event.Event payload,
                                              int sourcePartition,
                                              int targetPartition)

For distributed topology, we need to track its upstream source subTask ID to correctly distinguish events from different partitions.

getPayload
