Node. An ndbd process, which stores a replica —that is, a copy of the partition (see below)
assigned to the node group of which the node is a member.
Each data node should be located on a separate computer. While it is also possible to host multiple
ndbd processes on a single computer, such a configuration is not supported.
It is common for the terms “node” and “data node” to be used interchangeably when referring to
an ndbd process; where mentioned, management nodes (ndb_mgmd processes) and SQL nodes
(mysqld processes) are specified as such in this discussion.
