However, for complex queries (not primary key lookups) Other means, such as JDBC or the mysql client.ĬlusterJPA is an adapter for OpenJPA that can also bypass JDBCĪnd MySQL Server, using ClusterJ for fast-track access to theĬluster. Other data definition operations these must be performed by some However, unlike JDBC, ClusterJ does not support table creation and Included in the dynamic library libnbdclient. Often referred to (in MySQL documentation and elsewhere) simplyĬlusterJ does not need to connect to a mysqld These paths are shown in the following API stack diagram: SQL, JDBC, and the MySQL Server entirely when it is more Significantly improve performance for some uses, bypassing Paths-JDBC or ClusterJ-to MySQL Cluster data,ĭepending on the type of operation to be performed. It can use either of two different access Not depend on the MySQL Server for data access. Similar in many ways to that employed by JPA. Of data access that is based on a domain object model, Provides an object view of the data in the database. Uses JDBC to connect to the MySQL Server. The JDBC implementation most often used with the MySQL Result set that you want to use in your program as objects.
