> Option to control how many items are read on cache load

> CASSANDRA-1417 added an option to save the key and/or row cache keys which is
> cool. However, for a row large cache it can take a long time to read all of
> the rows. For example I have a 400,000 item row cache, and loading that on
> restart takes a little under an hour.
> In addition to configuring the size of the row cache, and how often it should
> be saved to disk, I propose an option to control how many items are loaded on
> startup (or alternately only saving n items out of the full row cache to
> begin with).
