Work Description: jbonofre commented on issue #8757: [BEAM-7427] Fix
JmsCheckpointMark Avro Encoding
URL: https://github.com/apache/beam/pull/8757#issuecomment-576542230
I'm evaluating the following options:
0. Add a test with AvroCoder on checkpoint mark
1. use JmsRecord in the checkpoint instead of Message to ack. The issue is
how to "load" Message from JmsRecord.
2. use Session to ack instead of message. The Session stores the unack
messages, so the checkpoint mark could delegate to the session.
I'm evaluating the different options. I keep you posted soon.
