I hope this is the right platform to raise this question.
I want to set up a 3 Node Cluster with RF3. The data that i am holding isn't growing and is only used for read access, so I was thinking to have 3 nodes (on ec2, one in each availability zone), each holding the full dataset.
My question is how many Seeds do I need?
If I have one Seed and that Node goes down, how does the new node (the one that replaces the seed) figure out where to get the data from? Do I have to reconfigure the other nodes to become seeds?
Ideally, I want to autoscale, so based on the amount of read requests, I want to be able to launch new nodes on demand.
Sorry that might be a beginner questions, but I would be very grateful if someone could help me here.
