Let’s say that I launch 3 identical servers, each of which is running a zero node and an alpha node for HA’s sake. Now, in the Dgraph docs under the “HA Cluster setup using Docker Swarm” section, I see that all of the alpha nodes are connecting to the same zero node since they are passed the following flag:
My question is: what would happen in the case that server running the
zero_1 node becomes unavailable? Would the remaining alphas be able to find the other remaining zeros?
Also, would the remaining zeros be able to peer with each other? Because I also see that they are all passed this same flag:
If they are able to do so, will there be interruption to any transactions that are coming in to the remaining alpha nodes?
Thanks for any help and clarification, I really appreciate it.
