Class NewPartition

java.lang.Object

org.apache.beam.sdk.io.gcp.bigtable.changestreams.model.NewPartition

All Implemented Interfaces:

java.io.Serializable

@Internal
public class NewPartition
extends java.lang.Object
implements java.io.Serializable

Represent new partition as a result of splits and merges.

Parent partitions stop streaming and record their change stream continuation tokens. The tokens are collected to continue the stream from the new partition.
