@Internal
public interface UnslicingWindowProcessor<W>
extends WindowProcessor<W>

The UnslicingWindowProcessor is an optimized processing for unaligned windows.

A UnslicingWindowProcessor usually leverages the UnsliceAssigner to assign slices and calculate based on the window.

Note: Currently, the UnslicingWindowProcessor only support session time window.
