saved row cache doesn't save the cache
--------------------------------------
Key: CASSANDRA-2102
URL: https://issues.apache.org/jira/browse/CASSANDRA-2102
Project: Cassandra
Issue Type: Bug
Reporter: Matthew F. Dennis
Assignee: Matthew F. Dennis
saving row caches works by periodically iterating of the keySet() on the caches
and writing the keys for the cached contents to disk. The cache keys are
DecoratedKeys. DecoratedKeys contain a Token token and a ByteBuffer key. The
underlying buffer on the key gets reused so the contents change. This means
that all the cache entries have distinct tokens but only a handful of distinct
key values. This means that when the cache is loaded you only end up loading a
handful of keys instead of the ones actually in your cache.
