. The MGM node is started with the command NDB_MGMD.Data node: This type of node is used to hold the data of the cluster. The number of data nodes is related to the number of replicas, which is a multiple of the fragment. For example, for two replicas with two fragments per copy, there are 4 data nodes. There is no need to have more than one copy. The data node is started with the command ndbd.SQL node: This is the node that is used to access the

operating system. The communication between data nodes of the MySQL cluster is unencrypted and requires high speed bandwidth, so it is recommended that the cluster be built on a high-speed LAN, and it is not recommended to deploy this system across the network segment and across the public network.
