Could You please briefly describe, how does the feature work? I need
feature similar to queuePrefetch
(http://activemq.apache.org/per-destination-policies.html) per destination (not
whole connection). Is it something similar?
I've set `<default-consumer-window-size>0</default-consumer-window-size>`
on address but it looks, that not works (slow consumer is prefetching more
messages).
With URL `(tcp://127.0.0.1:61616)?consumerWindowSize=0` is's working as
expected, but as I said, I need this setting for particular address, not whole
connection.

> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 2.6.2

> Priority: Major
> Fix For: 2.7.0

>
> In ActiveMQ 5.x a very useful feature is the ability to configure a prefetch
> in a policy which then gets negotiated with an OpenWire client. This allows
> changing the default prefetch setting by destination which is important
> because different destinations will have different message types and data
> flows. It's very useful to be able to configure it on the broker so that
> each client doesn't need to configure their side and an administrator can set
> a reasonable default (where the broker is shared by multiple
> clients/customers)
> To do this in Artemis I'm proposing creating a new window size negotiation as
> part of the consumer creation. Essentially the address can be configured
> with a different default window size if desired and if the client does not
> set the window size then the new configured default will be sent to the
> client which can be used instead of the standard 1 MiB.
