11.5.4. Topology Change Headers

When using Hot Rod to access Red Hat JBoss Data Grid, response headers respond to changes in the cluster or view formation by looking for clients that can distinguish between different topologies or hash distributions. The Hot Rod server compares the current topology ID and the topology ID sent by the client and, if the two differ, it returns a new topology ID.
