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 8.0 releases through 8.0.27. NDB Cluster 8.0 is now available (beginning with NDB 8.0.19) as a General Availability release, and recommended for new deployments; the latest available release is NDB 8.0.26. NDB Cluster 7.6 and 7.5 are previous GA releases still supported in production; for information about NDB Cluster 7.6, see What is New in NDB Cluster 7.6. For similar information about NDB Cluster 7.5, see What is New in NDB Cluster 7.5. NDB Cluster 7.4 and 7.3 are previous GA releases still supported in production, although we recommend that new deployments for production use NDB Cluster 8.0; see MySQL NDB Cluster 7.3 and NDB Cluster 7.4.
