> In any scenario, `autoWatermarkInterval` should not be less than or equal to
> zero.
> First of all, this does not correspond to the meaning of
> `autoWatermarkInterval`.
> Second, in the case where `autoWatermarkInterval` is less than 0, we will not
> be able to register ourselves in
> `TimestampsAndPeriodicWatermarksOperator#open`, which will result in the
> water level of this stream being kept at the lowest level.
