Subject Re: Queue only push messages and no pull from the consumer?
Date Mon, 21 Nov 2011 14:31:12 GMT
I think you're referring to the prefetch limits:

Many messages (by default) will be sent to a consumer before an
acknowledgement is received by the broker.
Consumer can pull messages (if you really want that) by setting prefetch to

Ref. "ActiveMQ in Action" chapter 13.3.1: "If the prefetch is zero, the
consumer will pull messages from the broker and no push will be involved."
