In the sections that follow, we discuss known limitations in current releases of NDB Cluster as compared with the features available when using the MyISAM and InnoDB storage engines.

This information is intended to be complete with respect to the conditions just set forth. You can report any discrepancies that you encounter to the MySQL bugs database using the instructions given in Section 1.5, “How to Report Bugs or Problems”. Any problem which we do not plan to fix in NDB Cluster 7.5 is added to the list.

See Previous NDB Cluster Issues Resolved in NDB Cluster 8.0 for a list of issues in earlier releases that have been resolved in NDB Cluster 7.5.
