Sergio Bossa commented on CASSANDRA-9318:
-----------------------------------------
bq. This method initializes the variable but where is it read?
Alright, looks like {{queryStartNanoTime}} replaced the old {{start}} variable
in the latest rebase, let me fix that and check/rerun tests.
> 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.
