SlidingWindow in Resilience4J and Sentinel.

Comparing with Resilience4j, Sentinel has only one kind of sliding window, time based sliding window, is it necessary adding another kind of sliding window called count based sliding window like R4j?

The issue names no files, tests, or entry points. First compare Sentinel’s existing time-based sliding-window behavior with the Resilience4j approach, then determine the scope and compatibility requirements for a count-based window. Done would require an agreed design and implementation decision, but the issue does not define acceptance criteria.
