You are write about strong consistency with that calculation, but if I want to issue a QUORUM read just by itself, I would expect a majority of nodes to reply. How it was written might be immaterial to my use case of reading 'from a majority.' -- ----------------- Nate McCall Wellington, NZ @zznate CTO Apache Cassandra Consulting http://www.thelastpickle.com
