Preface and Legal Notices

This is the MySQL NDB Cluster Internals Manual, which contains information about the NDBCLUSTER storage engine that is not strictly necessary for running the NDB Cluster product, but can prove useful for development and debugging purposes. Topics covered in this Guide include, among others, communication protocols employed between nodes, file systems used by management nodes and data nodes, error messages, and debugging (DUMP) commands in the management client.

The information presented in this guide is current for recent releases of NDB Cluster 8.0 up to and including NDB Cluster 8.0.41, as well as the NDB Cluster 8.4 LTS series. Due to significant functional and other changes in NDB Cluster and its underlying APIs, you should not expect this information to apply to previous releases of the NDB Cluster software prior to NDB Cluster 7.5. Users of older NDB Cluster releases should upgrade to the latest available release of NDB Cluster 8.0, which is the most recent GA release series, or to the NDB Cluster 8.4 LTS series.

For more information about NDB Cluster 8.0, see What is New in MySQL NDB Cluster 8.0. For information about NDB Cluster 8.4, see What is New in MySQL NDB Cluster 8.4.
