Python SDK
The OpenText™ Analytics Database SDK supports writing UDxs of some types in Python 3.
The Python SDK does not require any additional system configuration or header files. This low overhead allows you to develop and deploy new capabilities to your database cluster in a short amount of time.
The following workflow is typical for the Python SDK:
Because Python has an interpreter, you do not have to compile your program before loading the UDx in the database. However, you should expect to do some debugging of your code after you create your function and begin testing it in the database.
When the database calls your UDx, it starts a side process that manages the interaction between the server and the Python interpreter.
This section covers Python-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 Python SDK.
Important
Your UDx must be able to run with the version of Python bundled with the database. You can find this with/opt/vertica/sbin/python3 --version. You cannot change the version used by the OpenText™ Analytics Database Python interpreter.
