Unsupported or Missing Features in MySQL Cluster-opracowanie

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 [429]
(or --binlog-format=MIXED [429]) when setting up cluster replication. See Section 17.6, “MySQL
Cluster Replication”, for more information.
