   8 - an external tool able to perform the 'difference' between two Redis servers. It's like 'diff', but against Redis servers, and the output is the set of commands needed to turn the first server into the second, suitable to be sent via netcat.

  10    $ ./redis-diff 192.168.1.1 192.168.1.2 > diff.txt
  11    $ cat diff.txt | nc 192.168.1.1 6379
  12    $ ./redis-diff 192.168.1.1 192.168.1.2
  13    $ # No output now the servers are identical

  15 This command should be smart and don't use too much memory, that is, take two connections at the same time against the two servers and perform the comparison key by key. Probably the initial "KEYS *" is unavoidable.
