MySQL Cluster Manager 1.4 User Manual  /  Preface and Legal Notices

Preface and Legal Notices

This is the User Manual for the MySQL Cluster Manager, version 1.4.8. It documents the MySQL Cluster Manager Agent and MySQL Cluster Manager Client software applications, which can be used to administer MySQL NDB Cluster, a version of the MySQL Database System (referred to hereafter as MySQL Server or simply MySQL) that incorporates the NDB storage engine for high availability and data redundancy in a distributed computing environment.

This manual does contain certain basic information about MySQL and MySQL NDB Cluster; however, it is not in any way intended as an exhaustive reference for either of these products.

Versions of MySQL NDB Cluster compatible with MySQL Cluster Manager are based on versions 7.5 and 7.6 of the NDB storage engine; these versions of MySQL NDB Cluster are known as MySQL NDB Cluster 7.5, and MySQL NDB Cluster 7.6, respectively. MySQL NDB Cluster functionality varies between MySQL NDB Cluster releases; MySQL Cluster Manager cannot supply or emulate MySQL NDB Cluster features that are not present in the version of the MySQL NDB Cluster software in use.

For complete information about MySQL Server and MySQL NDB Cluster, see MySQL NDB Cluster 7.5 and NDB Cluster 7.6.

Warning

MySQL Cluster Manager 1.4 supports MySQL NDB Cluster 8.0 on an experimental basis only and should not be used with MySQL NDB Cluster 8.0 in a production environment. Some examples of MySQL 8.0 features that are not supported are listed here:

  • The default_auth_plugin system variable.
