   > I added some tests with 1000 windows. However, there's a problem with them: the side input is empty and no elements are accessed. I think it's because of wrong windowing strategy: the side input is windowed using fixed-time windows, but the main input is not. Is my assumption correct? If so, how should we deal with this problem in your opinion?
   
   The main input window is meant to be mapped onto the side input window. This is where the runner asks the SDK to map the main window onto the side input window: https://github.com/apache/beam/blob/fd8d0c61917149844a80f92adf91e5b944b685ec/sdks/python/apache_beam/runners/worker/bundle_processor.py#L1777
