CONSUMER: Should block ACK/REJECT if is in Preview mode

[dshvedchenko]

1. either not ack/reject always
2. or have option for Developer , to block ack/reject for Preview

[jcart]

What about queues that have require ack disabled?

[dshvedchenko]

We have option REQUEQUE , when TRUE, disables ack at all

[jcart]

Right. This is the obvious solution but you have to consider that this is not deterministic -- nor is there probably a way to accomplish it without ack. The risk should be identified somehow.

NOTE: at plugin class we have ability to detect Preview Mode : getTrans().isPreview().
for Preview mode we will always requeue messages.
