Subject Re: Quorom consistency in a changing ring
Date Tue, 27 Apr 2010 00:30:48 GMT
Live nodes that have tokens indicating they should receive a copy of
data count towards write quorum.  This means if a node is down (not
decommissioned) the copy sent to the node acting as the hinted handoff
replica will not count towards achieving quorum.  If a token is moved,
it is moved.  It is not in 2 places at once.  If you are using
CL.QUORUM and it succeeds, it really is reading or writing RF / 2 + 1
