This is an extract from the Reference Manual for the MySQL Database System, version 5.1. It contains information about MySQL Cluster releases, through MySQL Cluster NDB 6.3.53, MySQL Cluster NDB 7.0.39, and MySQL Cluster NDB 7.1.28. Differences between minor versions of MySQL Cluster covered in this extract are noted in the present text with reference to the NDBCLUSTER storage version number (6.3.x, 7.0.x, 7.1.x); differences between versions of the MySQL Server 5.1 software, on which MySQL Cluster is based, are noted with reference to MySQL 5.1 releases (5.1.x). For license information, see the legal notice. This product may contain third-party code. For license information on third-party code, see Appendix A, Licenses for Third-Party Components.

This extract also contains historical information about older versions of MySQL Cluster that were also based on version 5.1 of the MySQL database system (MySQL 5.1 Cluster, MySQL Cluster NDB 6.1, MySQL Cluster NDB 6.2), although these older versions are no longer supported, maintained, or recommended for new deployments. This extract is not intended for use with older versions of the MySQL Cluster software due to the many functional and other differences between current versions (MySQL Cluster NDB 6.3, MySQL Cluster NDB 7.0, and MySQL Cluster NDB 7.1) and previous versions. This extract provides information that is specific to MySQL Cluster and is not intended to replace the MySQL 5.1 Manual, which provides additional information about MySQL 5.1 which may also be necessary for use of MySQL Cluster. If you are using MySQL Server 5.1 or an earlier release of the MySQL software, please refer to the appropriate manual. For example, MySQL 5.0 Reference Manual, covers the 5.0 series of MySQL software releases.

If you are using MySQL 5.5, please refer to the MySQL 5.5 Reference Manual.
