MySQL 8.0 Reference Manual
MySQL 8.0 Release Notes
The listing in this section provides information about
parameters used in the [mysqld] and
[api] sections of a
config.ini file for configuring NDB Cluster
SQL nodes and API nodes. For detailed descriptions and other
additional information about each of these parameters, see
Section 5.3.7, “Defining SQL and Other API Nodes in an NDB Cluster”.
For a discussion of MySQL server options for NDB Cluster, see Section 5.3.9.1, “MySQL Server Options for NDB Cluster”. For information about MySQL server system variables relating to NDB Cluster, see Section 5.3.9.2, “NDB Cluster System Variables”.
Note
To add new SQL or API nodes to the configuration of a running
NDB Cluster, it is necessary to perform a rolling restart of
all cluster nodes after adding new [mysqld]
or [api] sections to the
config.ini file (or files, if you are
using more than one management server). This must be done
before the new SQL or API nodes can connect to the cluster.
It is not necessary to perform any restart of the cluster if new SQL or API nodes can employ previously unused API slots in the cluster configuration to connect to the cluster.
