This chapter provides information about MySQL NDB Cluster, a high-availability, high-redundancy version of MySQL adapted for the distributed computing environment, as well as information specific to NDB Cluster 8.4 (NDB 8.4.0), based on version 8.4 of the NDB storage engine. See Section 25.2.4, “What is New in MySQL NDB Cluster 8.4”, for information about differences in NDB 8.4 as compared to earlier releases. See MySQL NDB Cluster 8.0 for information about NDB Cluster 8.0. Both NDB 8.0 and NDB 8.4 are intended for use in production environments. NDB Cluster 7.6 and 7.5 are previous GA releases still supported in production, although new deployments can and should use either of MySQL NDB Cluster 8.0 or 8.4.

NDB Cluster 7.4 and older release series are no longer supported or maintained.
