Subject Re: Reading quorum
Date Fri, 03 Jun 2011 21:26:55 GMT
It means waiting for at least Quorum responses including the one data request sent to the "closest"
replica. The other replicas are asked to return a digest of the data.

The responses are then reconciled and if a difference is detected columns with the highest
timestamps will be returned. 

Hope that helps.
