This section describes how to add MySQL Cluster data nodes “online”—that is, without needing to shut down the cluster completely and restart it as part of the process. This capability is available in MySQL Cluster NDB 7.0 (beginning with MySQL Cluster NDB 6.4.0) and later MySQL Cluster release series.
Important
Currently, you must add new data nodes to a MySQL Cluster as part of a new node group. In addition, it is not possible to change the number of replicas (or the number of nodes per node group) online.
