Work Description: jbonofre commented on issue #10644: [BEAM-7427]
Refactore JmsCheckpointMark to be usage via Coder
URL: https://github.com/apache/beam/pull/10644#issuecomment-577510523
In the last commit, I'm using a different approach.
Now, the messages are automatically ack on the JMS broker. The pending
messages stored in the checkpoint mark. As I don't have to ack the messages
"explicitly" anymore, I can now convert the JMS Message as Beam JmsRecord, and
so CheckpointMark is now serializable.
This commit needs some polish, but I wanted to share the rough idea with you.
Thoughts ?
