---------------------------------------------------------------------
- double --> int for thrift/avro
- -1 --> max int for special value (but it's still a special value)
- CLI support
- Schema migration should work now, only jmx changes worked with v1.
I think I got everything from
http://wiki.apache.org/cassandra/ConfigurationNotes down, but admit that I'm
nervous at the size of the patch.
Max int is slightly confusing in jconsole, but I don't have a strong opinion
between that and -1.

> 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).
