MySQL Cluster Manager 1.3 User Manual  /  Attribute Summary Tables

Appendix C Attribute Summary Tables

This appendix provides tables of configuration attributes, grouped according to their process type or by the section of the MySQL Cluster configuration file in which they appear. This information is current for MySQL Cluster NDB 7.3. For information regarding MySQL Cluster NDB 7.2 and earlier versions of MySQL Cluster, see Configuration of MySQL Cluster, and Configuration of MySQL Cluster NDB 6.1-7.1.

Each table provides the following information:

  • Name: The name of the attribute. The name of the attribute is linked to the attribute's full description in the online MySQL Cluster documentation.

  • Type/Units: The data type or unit by which the attribute is measured.

  • Range: The default value of the attribute if not set by the user, and the minimum and maximum values which can be set for the attribute.

  • Restart Type: The type of restart required for a change in value in this attribute to be applied in a running MySQL Cluster. The restart type is indicated in this column by an N for a node restart, or an S for a system restart. Data node attributes: The presence of an I in this column indicates that a data node must be restarted using the --initial option for a change to take effect.

    Attributes having restart type N can be changed using a rolling restart of the cluster, and thus can be changed at any time, even if the cluster is running. Changing an attribute whose restart type is S requires a complete shutdown of all cluster nodes, followed by a restart of the nodes once all of them have been stopped. Currently, such attributes can be set only before starting a cluster for the first time.
