An abstract superclass for <a href="http://mahout.apache.org/mahout-mr/apidocs/org/apache/mahout/cf/taste/model/JDBCDataModel.html?is-external=true" title="class or interface in org.apache.mahout.cf.taste.model"><code>JDBCDataModel</code></a> implementations, providing most of the common
functionality that any such implementation would need.
</p>
<p>
Performance will be a concern with any <a href="http://mahout.apache.org/mahout-mr/apidocs/org/apache/mahout/cf/taste/model/JDBCDataModel.html?is-external=true" title="class or interface in org.apache.mahout.cf.taste.model"><code>JDBCDataModel</code></a>. There are going to be lots of
simultaneous reads and some writes to one table. Make sure the table is set up optimally -- for example,
you'll want to establish indexes.
</p>
<p>
You'll also want to use connection pooling of some kind. Most J2EE containers like Tomcat provide
connection pooling, so make sure the <a href="http://docs.oracle.com/javase/7/docs/api/javax/sql/DataSource.html?is-external=true" title="class or interface in javax.sql"><code>DataSource</code></a> it exposes is using pooling. Outside a J2EE
container, you can use packages like Jakarta's <a href="http://jakarta.apache.org/commons/dbcp/">DBCP</a>
to create a <a href="http://docs.oracle.com/javase/7/docs/api/javax/sql/DataSource.html?is-external=true" title="class or interface in javax.sql"><code>DataSource</code></a> on top of your database whose <a href="http://docs.oracle.com/javase/7/docs/api/java/sql/Connection.html?is-external=true" title="class or interface in java.sql"><code>Connection</code></a>s are pooled.
