Subject Re: Restore with archive commitlog
Date Fri, 13 Dec 2013 17:34:43 GMT
As someone told you this feature was added by Netflix to work with Priam
(cassandra management tool). Priam itself uses it for several months only,
so I doubt if anybody uses this feature in production. Any way, you can
ping guys working on Priam. This is your best bet.
https://github.com/Netflix/Priam

Let us know if you can figure out how to use it.

Thank you,
  Andrey
