Work Description: thinhha commented on issue #8370: [BEAM-3489] add
PubSub messageId in PubsubMessage
URL: https://github.com/apache/beam/pull/8370#issuecomment-518045772
Hi @lukecwik, looks like the non-messageId coders are hard-coded in
`PubsubUnboundedSource`:
Line 1088 of
`beam/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/pubsub/PubsubUnboundedSource.java`:
```
@Override
public Coder<PubsubMessage> getOutputCoder() {
return outer.getNeedsAttributes()
? PubsubMessageWithAttributesCoder.of()
: PubsubMessagePayloadOnlyCoder.of();
}
```
This means that while the PubsubMessage is created with the messageId field
populated when using
`PubsubIO.readMessagesWithMessageId()`/`PubsubIO.readMessagesWithAttributesAndMessageId()`
, this field does not show up in the subsequent step.
Looks like `setNeedsAttributes` is a required field. I'm not sure how to
change `getOutputCoder()`
without breaking something.
How do you think this case can be handled?
