MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6

Chapter 21 MySQL NDB Cluster 7.5 and NDB Cluster 7.6

This chapter provides information about MySQL NDB Cluster, a high-availability, high-redundancy version of MySQL adapted for the distributed computing environment which enables running several computers with MySQL servers and other software in a cluster. This chapter also provides information specific to NDB Cluster 7.5 releases through 5.7.44-ndb-7.5.35 and NDB Cluster 7.6 releases through 5.7.44-ndb-7.6.31, both of which are previous General Availability (GA) releases still supported in production. The latest available releases of these are 5.7.44-ndb-7.5.34 and 5.7.44-ndb-7.6.30, respectively. A more recent NDB Cluster stable release series uses version 8.0 of the NDB storage engine (also known as NDBCLUSTER). NDB Cluster 8.0, now available as a General Availability (GA) release beginning with version 8.0.19, incorporates version 8.0 of the NDB storage engine; see MySQL NDB Cluster 8.0, for more information about NDB 8.0. NDB Cluster 8.4 (NDB 8.4.0), based on version 8.4 of the NDB storage engine, is also available as an LTS release. See What is New in MySQL NDB Cluster 8.4, for information about differences in NDB 8.4 as compared to earlier releases. Previous GA releases NDB Cluster 7.4 and NDB Cluster 7.3 incorporated NDB versions 7.4 and 7.3, respectively. NDB 7.4 and older release series are no longer supported or maintained. Both NDB 8.0 and NDB 8.1 are supported in production, and are recommended for new deployments.
