[Task]: Update Python slowly updating side input example #35935
Description
What needs to happen?
https://beam.apache.org/documentation/patterns/side-inputs/ is missing a side input pattern for Python
When doing this, we should factor in #35934 (and probably use Latest.Globally.without_defaults() and test on Dataflow)

Hi 👋, I’d love to work on this issue as my first contribution to Apache Beam. I’m comfortable with Python and excited to dive in. Please let me know if there are any specific expectations or tips for getting started. Thanks!

Basically, you can add a new example to the
Slowly updating global window side inputspart. But before you do that, you should fix #35934 first.ankitkumarrain commentedon Sep 27, 2025

@damccorm I’m exploring this issue and noticed the side input patterns page currently shows examples for other SDKs but lacks a Python pattern.
I’m planning to add a Python example demonstrating the side input pattern using
Latest.Globally().without_defaults()as suggested, and include it in the documentation page.Could you confirm if the changes should go in the documentation under
documentation/patterns/side-inputsand whether an example pipeline file should also be added in the Python SDK examples?shubhdevelops commentedon Mar 6, 2026
Hi! I’ve opened a PR addressing this issue by adding a Python example for the “Slowly updating global window side inputs” section in the documentation.
The example demonstrates creating and using a side input with
Latest.Globally().without_defaults(). Please let me know if any improvements or adjustments are needed.shubhdevelops commentedon Mar 6, 2026

Hi! I'd like to update the Python slowly updating side input example. I'll review the current example, bring it up to date with current Beam Python SDK patterns, and make sure it runs correctly. Happy to submit a PR once I've verified the updated example end-to-end.
