    System Variable No
    Status Variable No

    Notes

    DESCRIPTION: Enable NDB Cluster (if this version of MySQL supports it)

    Disabled by --skip-ndbcluster.

    Property Value

    The NDBCLUSTER storage engine is necessary for using NDB Cluster. If a mysqld binary includes support for the NDBCLUSTER storage engine, the engine is disabled by default. Use the --ndbcluster option to enable it. Use --skip-ndbcluster to explicitly disable the engine.

    It is not necessary or desirable to use this option together with --initialize. Beginning with NDB 7.5.4, --ndbcluster is ignored (and the NDB storage engine is not enabled) if --initialize is also used. (Bug #81689, Bug #23518923)

    DESCRIPTION: Set to OFF to keep ALTER TABLE from using copying operations on NDB tables

    Property Value

    Let ALTER TABLE and other DDL statements use copying operations on NDB tables. Set to OFF to keep this from happening; doing so may improve performance of critical applications.
