What is the process when a node goes down and then restarts? Say backups = 1. We have node A that is primary for some key, and node B that is back up.
Node A goes down and then restarts after 5 min. What are the steps? 1) Node A is servicing all traffic for key X 2) Node A goes down 3) Node B starts serving all traffic for key X (I guess the clients detect the failover and start calling node B ) 4) Node A comes back up 5) WAL replication is initiated What happens next? When does node A become the primary again? How are in-flight updates happen?
