17.1.6.6. Unsupported or Missing Features in MySQL Cluster

A number of features supported by other storage engines are not supported for NDB tables. Trying to use any of these features in MySQL Cluster does not cause errors in or of itself; however, errors may occur in applications that expects the features to be supported or enforced:

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.
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.

Note

See Section 17.1.6.3, "Limits Relating to Transaction Handling in MySQL Cluster", for more information relating to limitations on transaction handling in NDB.
