> I had a proposed fix to clear the DoFnInvoker cached window args between bundles, however without the overall state cache being enabled this would result in re-fetching side inputs from the runner for each bundle. This might have a negative impact on streaming performance in particular where bundles are generally short-lived. Isn't this necessary for correctness, though? It seems like what we are doing today is basically just caching with bad refresh guarantees.
