Subject [GitHub] incubator-metron issue #143: METRON-197: Validation should be the last step ...
Date Mon, 06 Jun 2016 18:28:01 GMT
Github user james-sirota commented on the issue:

    https://github.com/apache/incubator-metron/pull/143
  
    If a message or a tuple fails validation then the associated message should get routed
to a dead letter queue.  I believe there is a different PR that is required to get the dead
letter queue established.  The tuple should be acked, though.  We need to differentiate between
if the tuple is failed due to not being able to be parsed vs. not validated.  So if we fail
based on parser issues then we need to ack for validation issues and then land the message
in the dead letter queue.  The important thing is for the messages that fail validation not
to go through the rest of the pipeline.
