[jira] [Commented] (BEAM-11828) JmsIO is not acknowledging messages correctly

["Boyuan Zhang (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-11828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17333402#comment-17333402 ] 

Boyuan Zhang commented on BEAM-11828:
-------------------------------------

Talking to one customer regarding to the same problem, the customer found that there is a high chance that the reader.close() is called before CheckpointMark.finalizaCheckpointMark() is called, but  CheckpointMark.finalizaCheckpointMark() requires the reader still holds the session. I think it's intended that the reader is closed before the runner tries to finalize the checkpointMark. It indicates a implementation problem inside JmsIO.

> Hello,
> We noticed that messages consumption via JmsIO does not acknowledge messages properly.
> Some messages are never acknowledged which results in data loss.
> So when do messages get acknowledged by JmsIO?
> How do We make sure all messages are being acknowledged?
>  
> Best regards,
