Re: Cluster not accepting insert while one node is down

Hi Traian, There is your problem. You are using RF=1, meaning that each node is responsible for its range, and nothing more. So when a node goes down, do the math, you just can't read 1/5 of your data. This is very cool for performances since each node owns its own part of the data and any write
