You should not use the row cache and the key vacumed on the same cf. If that is what you are doing it explains your numbers. Some docs suggest you can use them together but in practice I have seen when this is done the key cache rate drops to near 0.

Recently I have been seeing a terrible key cache hit rate (around 1-3%) with a 98% row cache hit rate. The seed node appears to take higher traffic than the other nodes (approximately twice) but I believe I have astyanax configured properly with ring describe and token aware. Any ideas or steps on how to debug? I also see high GC load. Perhaps I need more nodes?
