             Summary: Rebalance JCA RA inflow connections when cluster topology changes
                 Key: ARTEMIS-293
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-293
             Project: ActiveMQ Artemis
          Issue Type: New Feature
    Affects Versions: 1.1.0
            Reporter: Justin Bertram
            Assignee: Justin Bertram
             Fix For: 1.1.1


The inflow connections for an MDB (or other JCA inflow component) are typically long-lived. This is normally a good thing. However, when MDBs are consuming messages from a remote cluster and the topology of that cluster changes (i.e. a node is added to increase capacity or removed for maintenance) the inflow connections don't react in an efficient way. The RA should detect topology changes and re-balance the inflow connections across the new topology.
