The Kodo JDO Performance Pack is a suite of features that enhance the speed and functionality of the Kodo runtime. The Performance Pack is included in all Enterprise Edition licenses, or can be purchased separately. Contact firstname.lastname@example.org for details.
In addition to connection pooling and prepared statement caching, Kodo can be configured to employ SQL batching to speed up JDBC updates. By default, SQL batching is enabled for any JDBC driver that supports it. When batching is on, Kodo JDO automatically orders its SQL statements to maximize the size of each batch. This can result in large performance gains for transactions that modify a lot of data.
SQL batching is configured through the system DBDictionary, which is controlled by the kodo.jdbc.DBDictionary configuration property. The example below shows how to enable and disable SQL batching via the configuration properties file.
