[jira] [Commented] (CAMEL-3424) IdempotentConsumer EIP - Make it easier for end users to dicate onDuplicate

["Claus Ibsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-3424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13018820#comment-13018820 ] 

Claus Ibsen commented on CAMEL-3424:
------------------------------------

The full monty would be to allow a sub-route for onDuplicate

So you can do something like
{code}
idempotentConsumer XXX
   onDuplicate
      to bean:duplicate
   end
   to YYY
   to ZZZ
end
{code}

> Currently you would have to subclass IdempotentConsumer and add custom logic in {{onDuplicateMessage}}.
> End users may want to let some duplicates pass-through. So maybe we should have {{onDuplicateMessage}} return a boolean so we can determine what to do.
> If it returns {{false}} (default) the message will be dropped. If it returns {{true}} the message is allowed and is continued to route.
> We should then allow to set a custom predicate which can determine the onDuplicateMessage logic.
