Subject [jira] Commented: (SYNAPSE-593) Specifying a receiving sequence for sent messages
Date Mon, 09 Nov 2009 05:42:32 GMT

    [ https://issues.apache.org/jira/browse/SYNAPSE-593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12774867#action_12774867
] 

Supun Kamburugamuva commented on SYNAPSE-593:
---------------------------------------------

Yes I thought about this approach as well. But if we want to call several services based on
the previous result then we have to implement a complex logic in the out mediator to filter
out what are the responses for the particular request messages. 

But with my approach the logic is clean and easy to implement. Also in some cases we may not
be able to determine what are the responses for some requests. 

The way service chaining done in the example you've mentioned seems like a hacked up way.
Not something supported and embraced by synapse. 

Thanks,
Supun..

> If a receiving sequence is specified for send mediator, the response can be directed
to this sequence. This way we can achieve service chaining with normal non-blocking transport
calls. 
> I'm attaching a patch that introduce this feature. Please have a look and provide your
feed back.
