   # You can configure the slow log with two parameters: one tells Redis
   # what is the execution time, in microseconds, to exceed in order for the
   # command to get logged, and the other parameter is the length of the
  
positive.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.

negative.code: # Automatic rewrite of the append only file.
  # Redis is able to automatically rewrite the log file implicitly calling
  # BGREWRITEAOF when the AOF log size will growth by the specified percentage.
  #
  # This is how it works: Redis remembers the size of the AOF file after the
  # latest rewrite (or if no rewrite happened since the restart, the size of
  # the AOF at startup is used).
