Subject Re: Is LOCAL_QUORUM as strong as QUORUM?

Well it depends on the requirements. If you use any combination of CL with
EACH_QUORUM it means you are accepting the fact that you are ok if one of
the DC is down. And in your scenario you care more about DCs being
consistent even if writes were to fail. Also you are ok with network

I think there is a broader design question here and you might be able to
solve it with LOCAL_QUORUM if you handled it at application or load
balancing layer. Is this active/active data center? What's your actual
requirements? Are these external clients that can go to any data center?
