Hi, is it possible the get somehow the messageId field of a Pub/Sub message in a DoFn after using the PubSubIO Beam source to read the messages?
I need the default id which was assigned by the Pub/Sub service. I want to log it for debugging purposes. Using a custom attribute for the unique id and the withIdAttribute() method is not possible for me, because I have no influence on the publisher in this case. I use the 2.2.0 version of the Dataflow Java SDK. Thanks, Csabi
