> Currently, both the CF data, and the secondary index data are stored within the same folder on disk. Being able to split these into separate folders could be a great improvement with performance. With our data, and secondary index, we will query the index a lot more, so can optimise hardware for the two traffic shapes coming through.
> Something like /Keyspace/CF/indexes/indexname/*.db
> Not too sure how much would be involved to change this, but I would imagine fairly cheap cost to reward.
