Foreign key constraints.  The foreign key construct is ignored, just as it is in MyISAM tables.

Index prefixes.  Prefixes on indexes are not supported for NDBCLUSTER tables. If a prefix is used as part of an index specification in a statement such as CREATE TABLE, ALTER TABLE, or CREATE INDEX, the prefix is ignored.

OPTIMIZE operations.  OPTIMIZE operations are not supported.

Beginning with MySQL Cluster NDB 6.3.7, this limitation has been lifted. See Section 17.1.5.11, “Previous MySQL Cluster Issues Resolved in MySQL 5.1, MySQL Cluster NDB 6.x, and MySQL Cluster NDB 7.x”, for more information.

LOAD TABLE ... FROM MASTER.  LOAD TABLE ... FROM MASTER is not supported.

Savepoints and rollbacks.  Savepoints and rollbacks to savepoints are ignored as in MyISAM.

Durability of commits.  There are no durable commits on disk. Commits are replicated, but there is no guarantee that logs are flushed to disk on commit.

Replication.  Statement-based replication is not supported. Use --binlog-format=ROW (or --binlog-format=MIXED) when setting up cluster replication. See Section 17.6, “MySQL Cluster Replication”, for more information.

InnoDB plugin not supported.  Currently, MySQL Cluster is not compatible with the InnoDB Plugin. You must use the version of InnoDB that is supplied with the MySQL Server. See Section 17.2.1, “MySQL Cluster Multi-Computer Installation”, for information about enabling InnoDB storage engine support with MySQL Cluster.
