> With the recent changes introduced in
> https://issues.apache.org/jira/browse/FLINK-7293, the code paths between
> event- and processing-time handling are very close. This gives an opportunity
> to unify the 2 paths.
> To do this when operating in processing time, the user will specify an
> interval (like the watermark interval in event time), during which elements
> will be buffered, and only when this interval expires, the elements will be
> emitted. This is the same as the case of event-time, where elements between
> watermarks are buffered.
> This change will remove the need to register a processing time timer for
> every millisecond and it will also allow to emit timed-out patterns in
> processing time without having to wait for the "next" element to arrive.
