Hi, We have cassandra in production in three data centers with five nodes each. We are getting rid of one of the data centers, so I want to reconfig my cluster to two data centers, seven nodes each. I first need to shut down DC3. I have already shut down traffic to DC3 and am running repairs. My priority #1 is to maintain the stability of overall cluster (the two live data centers). Some data loss is tolerable, but it will be ideal if I can avoid that.
What is the best way to decommission entire data center? Should I issue decommission to the nodes one by one? Will that put additional load on remaining nodes in DC3? Or should I just shut them down and then run removetoken for these nodes? Or is there a better way? Thanks in advance, Hiren Shah
