+ Determines how often Cassandra saves the cache to the '''saved_caches_directory'''. Saved
caches greatly improve cold-start speeds, and is relatively cheap in terms of I/O for the
key cache. Row cache saving is much more expensive and has limited use.
  
  Defaults are: '3600' seconds (1 hour) between saves of the key cache, and '0' (disabled)
row cache saving.
