There used to be a ZERO consistency level but it was removed because it was harming more people than it was helping. If what you want is very high availability, i.e. being able to write even if the sole replica (in your RF=1 case) is down, then what you want to use is CL ANY. If you don't want to

Is there any mechanism that would allow me to write to Cassandra with no blocking at all? I spent a long time figuring out a problem I encountered with one node in each datacenter: LA, and NY using SS RF=1 and write consistency 1. My row keys are -mm-dd-h so basically for every hour a row woul
