Tsz-wo Sze commented on RATIS-632:
----------------------------------

[~ljain], thanks for clarifying it. I can see the logic form the patch but what 
are the meanings for these limitations #1 and #2?  What are the use cases?

We already have a mechanism by limiting the number of pending request to reject 
new client requests.  Why we need these new limitations?

> Leader should throw ResourceUnavailableException when follower lags in commit 
> index
