Package org.apache.beam.sdk.io.gcp.pubsub

Class PubsubIO.Write.PubsubBoundedWriter

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData
    Enclosing class:
    PubsubIO.Write<T>
    public class PubsubIO.Write.PubsubBoundedWriter
extends org.apache.beam.sdk.transforms.DoFn<PubsubMessage,​java.lang.Void>
    Writer to Pubsub which batches messages from bounded collections.

    Public so can be suppressed by runners.
