Aleksey Yeschenko commented on CASSANDRA-9318:
----------------------------------------------

bq. Yes. My point is that if we start by not accepting more than we can handle 
coordinator-side we (a) improve things immediately by a nontrivial amount and 
(b) we will have more clarity on what needs to be done replica-side.

Right. I'm all for flow control, in principle, and I'm not insisting on doing 
it comprehensively in one ticket, or even one version. Sorry if I made it 
non-clear. Not sure if it can be meaningfully done in 2.1, or that any of the 
suggested options are workable - will reply later.

> Bound the number of in-flight requests at the coordinator

>
> It's possible to somewhat bound the amount of load accepted into the cluster 
> by bounding the number of in-flight requests and request bytes.
> An implementation might do something like track the number of outstanding 
> bytes and requests and if it reaches a high watermark disable read on client 
> connections until it goes back below some low watermark.
> Need to make sure that disabling read on the client connection won't 
> introduce other issues.
