Description

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.
