Ariel Weisberg commented on CASSANDRA-7392:
-------------------------------------------
I remembered a neat hack you can use to get fast CAS on a field without having
to use unsafe or even AtomicReferenceFieldUpdater. The Atomic<Type> classes
aren't final so you can use them as the base class for something like OpState
:-) That gets you one free field with no indirection or bizarre Java plumbing.
Well only moderately bizarre.
> Abort in-progress queries that time out

> Key: CASSANDRA-7392
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7392
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Jonathan Ellis
> Assignee: Stefania
> 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.
