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
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.
This chapter contains information about NDB Cluster 7.3 releases through 5.6.51-ndb-7.3.33 as well as NDB Cluster 7.4 releases through 5.6.51-ndb-7.4.39. The latest available releases of these are 5.6.51-ndb-7.3.33 and 5.6.51-ndb-7.4.38, respectively. NDB Cluster 8.0 is now available as a General Availability release, and recommended for new deployments; for information about NDB Cluster 8.0, see What is New in MySQL NDB Cluster. NDB Cluster 7.6 and 7.5 are previous GA releases still supported in production. For information about NDB Cluster 7.6 and 7.5, see What is New in MySQL NDB Cluster.
