--------------------------------------------------------------------
Maybe. I haven't reproduced this yet. There are indexes in the schema. I have a
3-node cluster running in EC2 right now with a 256 gigabytes loaded per node.
[~llambiel] can you ping me in IRC and maybe we can work trying to get it to do
what you are seeing?
One caveat. I couldn't get Ops Center pointed at these three nodes. 2 of the 3
are advertising their internal interfaces to Ops Center so it can't reach them.

> After upgrading our cassandra staging cluster version from 2.1.6 to 2.1.7,
> the average load grows from 0.1-0.3 to 1.8.
> Latencies did increase as well.
> We see an increase of pending compactions, probably due to CASSANDRA-9592.
> This cluster has almost no workload (staging environment)
