Tsz-wo Sze commented on RATIS-1376:
-----------------------------------
The sliding window has to cache all the outstanding requests so that it can
retry non-acked the requests. Similarly, HDFS pipeline has a data queue which
also caches all the outstanding requests.
We probably should limit the total size of the outstanding requests in the
sliding window.

> [~szetszwo] I find the main used memory caused by
> SlidingWindow#Client#requests, because when send DataStreamWindowRequest with
> data, SlidingWindow#Client#requests will hold DataStreamWindowRequest until
> receive reply. Because DataStreamWindowRequest has data, so the memory used a
> lot. Still do not know how to improve it. Not sure whether SlidingWindow is
> necessary.
