The following improvements to NDB Cluster have been made in NDB Cluster 7.3:
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 Statement, and FOREIGN KEY Constraints.
End of ClusterJPA support. ClusterJPA is no longer supported beginning with NDB 7.3.18; its source code and binary have been removed from the NDB Cluster distribution.
ndb_restore—NDBT dependency removal. The dependency of ndb_restore on the
NDBTlibrary has been removed as of NDB 7.3.25. This library is used internally for development, and is not required for normal use; its inclusion in this program could lead to unwanted issues when testing.
The principal effect of this change for users is that ndb_restore no longer prints
NDBT_ProgramExit -following completion of a run. Applications that depend upon such behavior should be updated to reflect the change when upgrading.
Auto-Installer deprecation and removal. The MySQL NDB Cluster Auto-Installer web-based installation tool (ndb_setup.py) is deprecated in NDB 7.3.31, and is removed in NDB 7.3.32 and later. It is no longer supported.
ndbmemcache deprecation and removal.
ndbmemcacheis no longer supported.
ndbmemcachewas deprecated in NDB 7.3.31, and removed in NDB 7.3.32.
Node.js support removed. Beginning with the NDB Cluster 7.3.31 release, support for Node.js by NDB 7.3 has been removed.
Support for Node.js by NDB Cluster is maintained in NDB 8.0 only.
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 1.4.8 User Manual, for more information.
