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

All Implemented Interfaces:

Event

@Internal
public class PartitioningEvent
extends Object
implements Event

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

Method Detail

ofRegular

public static PartitioningEvent ofRegular(Event payload,
                                          int targetPartition)

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

ofDistributed

public static PartitioningEvent ofDistributed(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.
