What sort of management functionality does MySQL Cluster Manager provide?
Administrators are able to create and delete entire clusters, and to start, stop and restart the cluster with a single command. As a result, administrators no longer need to manually restart each data node in turn, in the correct sequence, or to create custom scripts to automate the process. MySQL Cluster Manager automates on-line management operations, including the upgrade, downgrade and reconfiguration of running clusters, without interrupting applications or clients accessing the database. Administrators no longer need to manually edit configuration files and distribute them to all other cluster nodes, or to determine if rolling restarts are required. MySQL Cluster Manager handles all of these tasks, thereby enforcing best practices and making on-line operations significantly simpler, faster and less error-prone.
