Based on MySQL Server 5.6. NDB Cluster 7.3 is based on MySQL Server 5.6, so that NDB Cluster users can benefit from MySQL 5.6's improvements in scalability and performance monitoring. As with MySQL 5.6, NDB Cluster 7.3 uses CMake for configuring and building from source. For more information about changes and improvements in MySQL 5.6, see What Is New in MySQL 5.6.
Foreign keys. Tables created using the
NDBstorage engine version 7.3.0 and later provide support for foreign key constraints. (This includes all NDB Cluster 7.3 releases.) For general information about how MySQL 5.6 and NDB Cluster 7.3 handle foreign keys, see FOREIGN KEY Constraints. For syntax and related information, see CREATE TABLE Syntax, and Using FOREIGN KEY Constraints.
NDB Cluster 7.3 is also supported by MySQL Cluster Manager, which provides an advanced command-line interface that can simplify many complex NDB Cluster management tasks. See MySQL™ Cluster Manager 1.4.7 User Manual, for more information.
