Subject [jira] [Commented] (AMQ-3707) Dynamic Failover Client Connection Params Broker Side Attribute
Date Thu, 09 Feb 2012 11:29:00 GMT


Gary Tully commented on AMQ-3707:

it may be better to leave these options as part of the failover transport as they are client
specific options.
Something like this exists for discovered transports{{discovery:(multicast://default)?initialReconnectDelay=100&discovered.closeAsync=false"}}.

I think it makes sense to use the same mechanism for failover updates as this is a form of

> Given that dynamic failover allows for the addition and removal of brokers from a list
of available connections at the client, I would suggest that an attribute be made available
on the broker to define what connection options a client should use when connecting to a given
