Bruce Snyder updated AMQ-2375:
------------------------------
Fix Version/s: 5.5.0
(was: 5.4.1)
> Allow a group preference scheme for failover urls
> -------------------------------------------------
>
> Key: AMQ-2375
> URL: https://issues.apache.org/activemq/browse/AMQ-2375
> Project: ActiveMQ
> Issue Type: Improvement
> Components: JMS client
> Environment: All
> Reporter: Andreas Gies
> Fix For: 5.5.0
>
>
> This enhancement request comes from working with a network of brokers, where
> each node in itself has a master/slave fault tolerant configuration.
> In a 2x2 setup currently you would have a failover url on the client side
> consisting of 4 single urls (2 masters, 2 slaves). Once a broker dies the JMS
> client would reconnect
> using one of the 4 urls either randomly chosen or in sequence of the url
> definition.
> That might cause the client to reconnect to a broker that belongs to the
> other master/slave pair. As master/slave is designed to preserve the session
> state etc, it would be preferable
> that the client tries to connect to the new master in its own master/slave
> group and only if that fails, connect to another broker.
> I would imagine a nested scheme of configurations, something like:
> failover:(failover:(master1,slave1)?randomize=false,failover:(master2,slave2)?randomize=false)?randomize=true
>
> instead of
> failover:(master1,slave1,master2,slave2)
