We have 2 dc in active/standby model. At any given point if we want to switch to standby dc, how will we make sure that data is consistent with active site? Note that repair runs at its scheduled time.
I am thinking of below approaches : 1.Before switching run the repair (although it assure consistency mostly but repair itself may take long time to complete) 2. Monitor the dropped message bean : If no message dropped since last successful repair then it is good to switch without running repair. 3. Monitor the hints backlog (files in hint directory), if no backlog then it is good to switch without running repair. I am interested to know how other people are solving this issue and make fast switch-over assuring consistency. -- regards, Laxmikant Upadhyay
