Claus Ibsen commented on CAMEL-2140:
------------------------------------
Currently the timeout and size is a fixed value, which frankly is much easier
to configure in Spring XML as its just an attribute on the XML tag.
I wonder if the best option is to just introduce headers which can override
these settings
{{Exchange.AGGREGATE_COMPLETION_TIMEOUT}}
{{Exchange.AGGREGATE_COMPLETION_SIZE}}
The problem is to keep this per correlation group. The timeout is possible as
its a build in feature into the TimeoutMap Camel uses under the covers.
The size however is currently a global setting. That can be changed to
introduce a Map based as well so you can override this and have it per
correlation key.

> dynamically setting the batchsize/timeout etc from header or dynamic
> expression is not straight forward.
> I would expect something like this:
> from("direct:a").aggregate(header("CLASSID")).batchTimeout(header("NUMBEROFSTUDENTS")).to("mock:result")
> or
> from("direct:a").aggregate(header("CLASSID")).setProperty(Exchange.BATCH_TIMOUT,header("ESTIMATION")).to("mock:result")
