Class NODES

java.lang.Object

org.infinispan.server.resp.RespCommand

org.infinispan.server.resp.commands.cluster.NODES

All Implemented Interfaces:

Resp3Command

public class NODES
extends RespCommand
implements Resp3Command

`CLUSTER NODES` command.

A command that uses the current CacheTopology and ConsistentHash to retrieve information about the nodes. The response slightly changes with the node executing the command, as it is necessary to identify itself. The execution is broadcast for nodes in the topology to identify themselves. So the response are cached according to the node that executed the command and the topology.
