-------------------------------------------
Hello,
I tend to agree with Claus. Using a marker header would not help much in the
scenario where you want to pre-complete a group to obey a maximum size limit.
I started to prototype a sample code some time ago, I can share this with you
if this may help.
Regards,
Sebastien.

> Components: camel-core, eip

> Reporter: Susan Javurek
> Assignee: Ben O'Day
> Fix For: Future

>
> There is a way to do this by creating a "trigger" exchange that is handled in
> a special way by the aggregation strategy and a completion predicate. But
> this solution is quite intrusive and painful to write.
> It would actually be much easier if the AggregateProcessor would implement
> and expose the following methods:
> public void forceCompletionOfGroup(String key)
> public Expression getCorrelationExpression()
> This way, it becomes possible to control "externally" an aggregator without
> having to implement some intrusive logic.
