Is there any concern of data loss here? Typically Beam is supposed to handle any threading or async itself. I'm thinking of the case where async is delayed, and Beam thinks a given element is completed, but it hasn't actually been sent to pulsar.

I agree with the concerns here, I've seen very troublesome async writers in Beam that were prone to loosing data. I suppose in this case it depends on the behavior of producer.flush() in finishBundle(). Does it block until all pending messages are send? If so, I'd suggest to add some comments to clarify.

Wondering, is there a lack of test coverage if you could change the producer from sync to async without having to change tests? |
