Marcus Eriksson commented on CASSANDRA-5357:
--------------------------------------------

OK, ill refactor a bit then, stand by for new patch

My use case was the "give me the last hour of data"-slices for time series data 
etc, not limit queries

> Query cache / partition head cache

> I think that most people expect the row cache to act like a query cache, 
> because that's a reasonable model.  Caching the entire partition is, in 
> retrospect, not really reasonable, so it's not surprising that it catches 
> people off guard, especially given the confusion we've inflicted on ourselves 
> as to what a "row" constitutes.
> I propose replacing it with a true query cache.
