UDFs can be implemented in any of the following APIs:
Tutorial
The following tutorial details the implementation & execution of distributed User-Defined Functions (UDFs) in the Python API. Also provided are examples of UDFs, including a simple table copy and a more complex integration into a machine-learning library's demo program.
UDF Prerequisites
- The system_admin role (for managing procs) or Proc Level Permissions (for managing procs as a non-admin). See Managing Users & Roles for more information on setting roles and permissions
- Kinetica UDF APIs; these can be downloaded from GitHub. See one of the API references below for installation instructions.
Development

Compatibility
Each UDF API should be compatible with the corresponding minor release of the database; e.g., the Python UDF v7.1 API is compatible with a Kinetica v7.1 database.
