NDB Cluster Configuration Files NodeId  is the preferred parameter name to use when identifying API nodes. ( Id  continues to be supported for backward compatibility, but is now deprecated and generates a warning when used. It is also subject to future removal.) Specifies which data nodes to connect. The  NodeId  is an integer value used to identify the node in all cluster internal messages. The permitted range of values is 1 to 255 inclusive. This value must be unique for each node in the cluster, regardless of the type of node. In NDB 8.0.18 and later, data node IDs must be less than 145. If you plan to deploy a large number of data nodes, it is a good idea to limit the node IDs for API nodes (and management nodes) to values greater than 144. (Previous to NDB 8.0.18, the maximum supported value for a data node ID was 48.)

An alias,  Id , was used for this purpose in very old versions of NDB Cluster, and continues to be supported for backward compatibility; it is now deprecated and generates a warning when used, and is subject to removal in a future release of NDB Cluster.
