Subject Re: RecipientList without aggregation
Date Wed, 28 Mar 2012 21:33:48 GMT
Mario,

if you know in advance which beans will be consuming from the endpoint, you
could define them statically using Multicast, without the dynamism of
Recipient-List.  if you don't need to await responses from the Multicast
targets before continuing from the Multicast block to the next pipe in the
route, i think setting parallelProcessing=true and streaming=true, combined
with using the inOnly Message Exchange Pattern [1] for each target in the
Multicast, *might* work (committers - is this correct?).

however, i employed a different approach for a similar scenario where i
just need to dispatch a "fire-and-forget" event to a set of consumers.  i
used SEDA [2] queues with multipleConsumers=true for a lightweight
multicast.  if you want to, you could even combine outputs later on in a
"gathering" SEDA queue that funnels into an aggregator or other processor /
Enterprise Integration Pattern [3].

SEDA is probably my favorite component as there are some fun split/join
flows you can orchestrate with it.
