   # Warning: since Redis is pretty fast an outside user can try up to
   # 150k passwords per second against a good box. This means that you should
   # use a very strong password otherwise it will be very easy to break.

  # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
  # is reached? You can select among five behavior:
  # 
  # volatile-lru -> remove the key with an expire set using an LRU algorithm
  # allkeys-lru -> remove any key accordingly to the LRU algorithm
  # volatile-random -> remove a random key with an expire set
  # allkeys->random -> remove a random key, any key
  # volatile-ttl -> remove the key with the nearest expire time (minor TTL)
  # noeviction -> don't expire at all, just return an error on write operations
  # 
  # Note: with all the kind of policies, Redis will return an error on write
  #       operations, when there are not suitable keys for eviction.

negative.code: # that is rhashing, the more rehashing "steps" are performed, so if the
  # server is idle the rehashing is never complete and some more memory is used
  # by the hash table.
  #
  # The default is to use this millisecond 10 times every second in order to
  # active rehashing the main dictionaries, freeing memory when possible.
