Description

We are currently using PubSub Lite IO with Dataflow Runner.

Our Beam job is on streaming mode.

The read from a PubSub Lite subscription works correctly.

The sink to a PubSub topic doesn't work with the runner. 

When we take a look  on the job graph for the PubSubLite Write step (transform : org.apache.beam.sdk.io.gcp.pubsublite.PubsubLiteSink ) in the Google Cloud Console we don't see any writes.

When we check the topic we don't see any outputs.

Code works well on 2.27, 2.28, 2.29 Beam version.

Here is the code we used to do the check on version:

• 2.27 
• 2.28
• 2.29
• 2.30
• 2.31
• 2.33
• 2.33

 

// PubSubStreamingWriteJobOptions options =
        PipelineOptionsFactory.fromArgs(args).withValidation().as(PubSubStreamingWriteJobOptions.class);

options.setStreaming(true);

//set up file system
FileSystems.setDefaultPipelineOptions(options);




TopicPath topicPath = TopicPath.newBuilder()
        .setProject(ProjectId.of("[PROJECT ID]"))
        .setLocation(CloudZone.of(CloudRegion.of("[REGION]"), "[ZONE CHAR]"))
        .setName(TopicName.of("[TOPIC ID]"))
        .build();


PublisherOptions publisherOptions =
        PublisherOptions.newBuilder()
                .setTopicPath(topicPath)
                .build();

Pipeline pipeline = Pipeline.create(options);

pipeline.apply(TextIO.read()
                .from("gs://[BUCKET]/[OBJECT_PREFIX]*")
                .watchForNewFiles(
                        Duration.standardMinutes(1),
                        Watch.Growth.afterTimeSinceNewOutput(Duration.standardHours(1))))
        .apply(CREATE_PUB_SUB_LITE_MESSAGE_STEP, MapElements.into(TypeDescriptor.of(PubSubMessage.class)).via(file -> {
            Instant instant = Instant.now();
            Message message =
                    Message.builder()
                            .setData(ByteString.copyFromUtf8("message " + file))
                            .setEventTime(Timestamp.newBuilder()
                                    .setNanos(instant.getNano())
                                    .setSeconds(instant.getEpochSecond())
                                    .build())
                            .build();

            return message.toProto();
        }))
        .apply(SINK_PUB_SUB_LITE_MESSAGES_STEP, PubsubLiteIO.write(publisherOptions));
pipeline.run();

Can you help us to found the issue and fix the Beam version please?
