How does MySQL Cluster Manager ensure the cluster configuration remains consistent across all nodes in the cluster?
MySQL Cluster Manager supports asynchronous communication between each management agent in order to reliably propagate reconfiguration requests. As a result, configurations remain consistent across all nodes in the cluster. Any changes are only committed when all nodes confirm they have received the re-configuration request. If one or more nodes fail to receive the request, then an error is reported back to the client. By automating the coordination of re-configuration requests, opportunities for errors resulting from manually distributing configuration files are eliminated.
