This document discusses configuring MySQL for federated and cluster environments. It covers setting up a federated server to access remote databases, creating identical tables on the local and remote servers, and the components and configuration of a MySQL cluster including the management node, data nodes, SQL nodes, and using ndb_mgmd, ndb_mgm and mysqld processes.
