Ignore the first N datapoints that are passed in. This is typically used to achieve an initial alignment to step boundaries when using a deterministic sliding window approach like SDES.
Returns true if the state is the same as if it had been reset. This means that the state does not need to be stored and can just be recreated if a new values shows up. When processing a stream this is needed to avoid a memory leak for state objects if there are some transient values associated with a group by. This check becomes the effective lifespan for the state if no data is received for a given interval.
