What storage engines are supported by MySQL Cluster?
Clustering with MySQL is supported only by the NDB storage engine. That is, in order for a table to be shared between nodes in a MySQL Cluster, the table must be created using ENGINE=NDB (or the equivalent option ENGINE=NDBCLUSTER). It is possible to create tables using other storage engines (such as MyISAM or InnoDB) on a MySQL server being used with a MySQL Cluster, but these non-NDB tables do not participate in clustering; each such table is strictly local to the individual MySQL server instance on which it is created.
