The transporter's group number can be based on which availability domain is used, such that also SQL and other API nodes communicate with local data nodes in the same availability domain whenever possible. The [ndb_mgmd] section is used to ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-ndbinfo-locks-per-fragment.html
The locks_per_fragment table provides information about counts of lock claim requests, and the outcomes of these requests on a per-fragment basis, serving as a companion table to operations_per_fragment and memory_per_fragment. This table also ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-ndbinfo-operations-per-fragment.html
Since there are typically two fragment replicas, and assuming that this is so, each fragment_num value should appear twice in the table, on two different data nodes from the same node group. The operations_per_fragment table provides information ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-ndbinfo-table-distribution-status.html
The table_distribution_status table provides information about the progress of table distribution for NDB tables. is_reorg_ongoing Whether the table is currently being reorganized (1 if true) .
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-overview-requirements.html
Recall that, to maintain data consistency, an NDB Cluster shuts down when the last node in a node group fails. One of the strengths of NDB Cluster is that it can be run on commodity hardware and has no unusual requirements in this regard, other ...

For more information about data nodes, how they are organized in an NDB Cluster, and how they handle and store NDB Cluster data, see Section 25.2.2, “NDB Cluster Nodes, Node Groups, Fragment Replicas, and Partitions”. NDB Cluster is a ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-security-mysql-security-procedures.html
In this section, we discuss MySQL standard security procedures as they apply to running NDB Cluster. In general, any standard procedure for running MySQL securely also applies to running a MySQL Server as part of an NDB Cluster. First and foremost, ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-start-phases.html
This section provides a simplified outline of the steps involved when NDB Cluster data nodes are started. More complete information can be found in NDB Cluster Start Phases, in the NDB Internals Guide. These phases are the same as those reported in ...

Note To take the best advantage of direct connections in this fashion with more than two data nodes, you must have a direct connection between each data node and every other data node in the same node group. Setting up a cluster using direct ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-tcp-definition.html
Group When ndb_optimized_node_selection is enabled, node proximity is used in some cases to select which node to connect to. TCP/IP is the default transport mechanism for all connections between nodes in an NDB Cluster. Normally it is not necessary ...
