Quite possibly. But it will keep memory use in your shovel much more 
controlled, which has to be a good thing.

Well, if the publishing connection is in "flow" state then that just 
means that it would like to publish faster, but something (the 
downstream queue probably) can't keep up.

Ultimately you probably need more capacity in your destination brokers, 
if the source brokers are backing up.
