jConnect for JDBC 7.07 adds the SEND_BATCH_IMMEDIATE connection property.
When set to true, jConnect sends the parameters for the current row immediately after invoking PreparedStatement.addBatch(). This minimizes usage of client memory and gives the server more time to process the batch parameters.
The default SEND_BATCH_IMMEDIATE value is false, which, when set, signals jConnect to send the batch parameters only after invoking PreparedStatement.executeBatch(), as before.
