Benedict commented on CASSANDRA-9318:
-------------------------------------
This still leaves some questions, of varying import and difficulty:
* how can we easily block consumption of writes from clients without stopping
reads?
* how should we mandate (or encourage) native clients to behave:
** separate read/write connections?
** configurable blocking queue size for pending writes to avoid unbounded
growth?
** should timeouts be from time of despatch, or from time of submission to
local client?
* will we implement this for thrift clients?
> Bound the number of in-flight requests at the coordinator

> URL: https://issues.apache.org/jira/browse/CASSANDRA-9318
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Ariel Weisberg
> Assignee: Ariel Weisberg
> Fix For: 2.1.x, 2.2.x
>
>
> 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.
