14.4. User-Defined Functions Support

In Teiid Designer you can create, manage and use User-Defined Functions (UDFs). These functions allow you to perform simple or complex Java operations on your data during runtime. This is accomplished by deploying your custom UDF jars on your server and creating a scalar function representation of your function method to use in your view transformation. In the VDB Editor, you have the option of including your UDF jars as part of the VDB artifact. If included in the VDB, the jars will automatically be deployed to the server for you when the VDB is deployed.

When a UDF model is added to a VDB, each scalar function is interrogated and its referenced UDF jar (if available) is added to the VDB as well as shown in the UDF Jars tab in the editor
