Subject [jira] Reopened: (CASSANDRA-1966) Option to control how many items are read on cache load

Chris Burroughs reopened CASSANDRA-1966:
----------------------------------------


http://code.google.com/p/concurrentlinkedhashmap/issues/detail?id=21

has been completed so this is now feasible.  I presume Cassandra would still wait for the
1.2 release of CLHM.

> 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).
