Aleksey Yeschenko commented on CASSANDRA-7392:
----------------------------------------------
bq. I'm just envisioning here worker-thread checks to drop a
request-in-progress.
If you mean timeout checks sprinkled at reasonable intervals on the read path,
then that's the same thing I'm envisioning as well.
> Abort in-progress queries that time out

> Project: Cassandra

> Fix For: 3.x

>
> Currently we drop queries that time out before we get to them (because node
> is overloaded) but not queries that time out while being processed.
> (Particularly common for index queries on data that shouldn't be indexed.)
> Adding the latter and logging when we have to interrupt one gets us a poor
> man's "slow query log" for free.
