Function RM_AvoidReplicaTraffic

src/module.cpp:2278–2281

Returns true if some client sent the CLIENT PAUSE command to the server or * if Redis Cluster is doing a manual failover, and paused tue clients. * This is needed when we have a master with replicas, and want to write, * without adding further data to the replication channel, that the replicas * replication offset, match the one of the master. When this happens, it is * safe to failover the m

 * periodically in timer callbacks or other periodic callbacks.
