Chapter 4. Extending the JDBC Translator

4.1. Extensions

New custom Translators can be created by extending the JDBC Translator. This is one of the most common use-cases for custom Translator development and is often done to add support for JDBC drivers and database versions.
To design a JDBC Translator for any relational database management system (RDBMS) that is not already supported by Red Hat JBoss Data Virtualization, extend the org.teiid.translator.jdbc.JDBCExecutionFactory class in the translator-jdbc module. There are three types of methods that you can override from the base class to define the behavior of the Translator.
