[Gluster-devel] Choice of Translator question

[Krishna Srinivas]

Hi Gareth,

http://www.gluster.org/docs/index.php/Understanding_AFR_Translator

Check out if it clears your doubts.
Yes you can use stripe over afr to minimize the selfhealing time. But it will
have management overhead. Mail back your doubts if you have any.

Regards
Krishna
