There are a couple issues with the python SDK and side input patterns page here https://beam.apache.org/documentation/patterns/side-inputs/
1. Slowly updating global window side input doesn’t have a python example 2. Slowly updating side input using windows doesn’t have enough code to run the python example (first_timestamp, last_timestamp, interval, True) — ? sample_main_input_elements ? 3. Slowly updating side input using windows example doesn’t work in python DirectRunner due to https://github.com/apache/beam/issues/21103 I imagine most people are using DirectRunner to test out unfamiliar patterns
