Java SDK

The Vertica SDK supports writing Java UDxs of all types except aggregate functions. All Java UDxs are fenced.

You can download, compile, and run the examples; see Downloading and running UDx example code. Running the examples is a good way to verify that your development environment has all needed libraries.

If you do not have access to a Vertica test environment, you can install Vertica on your development machine and run a single node. Each time you rebuild your UDx library, you need to re-install it into Vertica. The following diagram illustrates the typical development cycle.

This section covers Java-specific topics that apply to all UDx types. For information that applies to all languages, see Arguments and return values, UDx parameters, Errors, warnings, and logging, Handling cancel requests and the sections for specific UDx types. For full API documentation, see the Java SDK Documentation.
