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.
