> Specifically
> - in ProcessElements, if there are multiple windows to consider each is processed sequentially with sequential state fetches instead of a bulk prefetch
> - onTimer method doesn't evaluate multiple timers at a time meaning that if multiple timers are fired at once each is processed sequentially without batched prefetching
