Pausing Traffic to and from Multiple Clusters
If a Broker serves as a gateway to multiple clusters, and you want to pause outbound traffic to all of the clusters, execute BrokerAdminClient.setClusterGatewayPause on the gateway Broker once for each remote cluster.
Similarly, if you want to halt inbound traffic to a gateway Broker from multiple remote clusters, execute BrokerAdminClient.setClusterGatewayPause on each remote gateway Broker.
