MySQL Cluster Connector for Java is a collection of Java APIs for writing applications against MySQL Cluster, including JDBC, JPA, and ClusterJ. These provide a number of different access paths and styles of access to MySQL Cluster data. Section 4.1.2, “Java and MySQL Cluster”, describes each of these APIs in more detail.
MySQL Cluster Connector for Java is included with MySQL Cluster source and binary releases beginning with MySQL Cluster NDB 7.1.1. Building MySQL Cluster Connector for Java from source can be done as part of building MySQL Cluster; however, it can also be built with Maven.
