I have a question about what can be expected after a cluster restart.
I have a cluster with three nodes, and the machine is a simple k-v store implemented as a map, with perhaps ~100 elements.
Everything is stable, and I stop all three nodes. Then they are all restarted. Some short time after ra:restart_server(Name, {Module, node()}) has returned ok, I do a leader_query to read a value that I know was in the kv store before the restart, but at this time it is not there (I get a proper no_such_key return value from my callback module, not an error). Then after timer:sleep(1000) I try the same leader_query, and now the item is there.
So my question is if this is expected?
