My understanding is that the coordinator will acknowledge the writes faster then they can actually be written. Eventually it will run out of buffer space.


Using CL.ONE makes it harder for the clients to flood the cluster with more writes than it can perform. As usual add more nodes to add more write throughput.

are you saying that CL.ONE is equally performant? or possibly better by
your comment that ZERO can be a serious resource hog?
