Subject [jira] [Commented] (AMQ-3707) Dynamic Failover Client Connection Params Broker Side Attribute
Date Tue, 11 Sep 2012 13:59:07 GMT


Gary Tully commented on AMQ-3707:

thinking that an attribute {code}clusterClientsURIQuery{code} on the transport connector would
make sense, it would get appended to whatever is the publishable address of the transport
for update cluster client information.
This avoids the transport server having to deal with the query parameters and leaves them

> 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
> Therefore a client with the following list of connections:
> Client connect string
> * failover://(tcp://somebrokerA:61616,tcp://somebrokerB:61616)
> And a broker with the following
> * (NEW) *clusterClientsConnectionParams="useCompression=true"*
> Would result in a client with the following connection list:
> * tcp://somebrokerA:61616?clusterClientsConnectionParams="useCompression=true"
> * tcp://somebrokerB:61616?clusterClientsConnectionParams="useCompression=true"
> And should a new broker be added to the cluster (if this option was set on each broker):
> * tcp://somebrokerA:61616?clusterClientsConnectionParams="useCompression=true"
> * tcp://somebrokerB:61616?clusterClientsConnectionParams="useCompression=true"
> * tcp://somebrokerC:61616?clusterClientsConnectionParams="useCompression=true"
