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. The most recent NDB Cluster release series uses version 8 of the NDB storage engine (also known as NDBCLUSTER) to enable running several computers with MySQL servers and other software in a cluster. 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. NDB Cluster 7.6 and NDB Cluster 7.5, still available as GA releases, use versions 7.6 and 7.5 of NDB, respectively. Previous GA releases still available for use in production, NDB Cluster 7.4 and NDB Cluster 7.3, incorporate NDB versions 7.4 and 7.3, respectively. NDB 7.2 and older release series are no longer supported or maintained.

This chapter contains information about NDB Cluster 7.5 releases through 5.7.38-ndb-7.5.27 and NDB Cluster 7.6 releases through 5.7.38-ndb-7.6.26, both of which are General Availability (GA) releases supported in production. The latest available rleases of these are 5.7.38-ndb-7.5.26 and 5.7.38-ndb-7.6.22, respectively.
