Subject Re: What Happens to Consistency if I kill a Leader and Startup it again?
Date Thu, 02 May 2013 12:12:30 GMT
Thanks for the answer. This is what I try to say:

time = t
Node A (Leader):  version is 100
Node B (Replica): version is 90

time = t+1
Node A (Killing):  version is 100 and killed
Node B (Replica): version is 90

time = t+2
Node A (Killed):  version is 100 and killed
Node B (Become Leader): version is 95 (we indexed something)

time = t+3
Node A (Started as Replica):  version is 100 and live
Node B (Leader): version is 95

so I think that leader will behind replica. Is there anything different for
such scenario?
