## org.apache.openjpa.jdbc.kernel
Class BatchingConstraintUpdateManager

    java.lang.Object
      org.apache.openjpa.jdbc.kernel.AbstractUpdateManager
          org.apache.openjpa.jdbc.kernel.ConstraintUpdateManager
              org.apache.openjpa.jdbc.kernel.BatchingConstraintUpdateManager

All Implemented Interfaces:
  UpdateManager, Configurable

    public class BatchingConstraintUpdateManager

extends ConstraintUpdateManager

Batch update manager that writes the SQL in object-level operation order. This update manager initiates a BatchPreparedStatementManagerImpl which will utilize the JDBC addBatch() and executeBatch() APIs to batch the statements for performance improvement.

This is the default plug-in class for UpdateManager to support statement batching. You can plug-in your own statement batch implementation through the following property:

       < property name="openjpa.jdbc.UpdateManager"
         value="org.apache.openjpa.jdbc.kernel.YourOperationOrderUpdateManager" />
