I was thinking of trigger-messages vs data-messages.

Then again we've just begun dabbling with AMQP as part of transitioning our legacy application to a new platform, so a n00b in the field.

We do have what you might consider hybrid messages, where we store incoming data in an object store and send a trigger-message with the key to process the data. This keeps the queue lean and makes it easy for support to inspect submitted data after it's been processed, to determine if we have a bug or it's garbage in garbage out.
