> I suggest to configure populate_io_cache_on_flush option for each column
> family. It should be configurable from cassandra-cli and should be stored in
> System keyspace.
> That could be useful if you have a few column families inside single keyspace
> and you need to fit in memory only one of them.
> Patch has been attached. I've been testing it on pseudo-cluster using ccm. So
> I don't have fully confidence about lack of bugs. Please carefully review
> that code.
