Hi Matvey,
The approach of throwing an exception and returning the message to the queue
in order to process another message that can be processed quicker is not a
good solution. It is prrocessing expense incurred for no real value.
I would rather create 2 queues or 1 virtual queue/topic in activemq and
direct payloads of lower size to one queue and the larger payloads to
another. Thene you can separate your consumers to process the messages more
optimally based on your specific requirements.
Note that the Camel route need not change and this would be a simple
configuration setting in activemq.xml
You may want to check this out.

Cheers,
