Sylvain Lebresne commented on CASSANDRA-7392:
---------------------------------------------
General approach lgtm from a quick glance but I'm gonna hand off review to
[~blerer] since my plate is a bit full and I don't want to delay review too
long.
Small aside: I'm really not a huge fan of having paths specific to tests in the
middle of actually used code (as in {{ReadCommand}}). I understand there isn't
a much easier way to test this currently and I don't oppose this in the short
term, but it would make me very happy if we could find a cleaner way to deal
with this in the longer run. Maybe we could have a way to mock up a
SSTableReader (and to inject it so it's used by queries), which would allow to
make it run very slowly. Or something like that.

>
> 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.
