Sylvain Lebresne commented on CASSANDRA-5357:
---------------------------------------------

bq. If you have a single row per partition, how much of the table you cache is 
purely a function of cache size.

If that was related to my remark above, I don't think I understood that 
sentence, sorry.

> 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.
