Subject [jira] [Commented] (AMQ-4017) Demand Forwarding Bridge uses value of asyncDispatch for advisory consumers
Date Tue, 04 Sep 2012 15:44:07 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447760#comment-13447760

IRC chat record with gtully:

17:14:06 raul: hey, quick question... what is the dispatchAsync on the network connector used
for? is it only used when listening for advisories?
17:24:05 gtully: raul: it is also used for local proxy consumers that will do the forwarding...
in fact, I don't think we should use that option for the advisory consumer, it should always
be async as a block would propagate back to the broker
17:29:30 raul: gtully, I think it's being used for the advisory consumer at least on 5.5.1:
DemandForwardingSubscription.startRemoteBridge, inside the 'demandConsumerInfo' ConsumerInfo
17:30:35 gtully: raul: it is, think that is a bug waiting to happen if folks use dispatchAsync=false

> The value of the dispatchAsync option on the networkConnector element is used when creating
the ConsumerInfo command that we dispatch to the remote broker with the aim of subscribing
to demand-related consumer advisories.
> A 'false' value means we risk blocking the remote broker if the local->remote broker
connection is blocked.
