We want to use fly to migrate our Elixir application.
We were able to configure our application as a cluster but we want to do the same for the Postgres application.
I created Postgres Cluster on two regions but the application are really slow.
❯ fly status -a brandkit-pg-st App Name = brandkit-pg-st Owner = brandkit Version = 4 Status = running Hostname = brandkit-pg-st.fly.dev Deployment Status ID = e20569c0-f788-c5c1-ddcb-26aea1dfe55c Version = v4 Status = successful Description = Deployment completed successfully Instances = 3 desired, 3 placed, 3 healthy, 0 unhealthy Instances ID TASK VERSION REGION DESIRED STATUS HEALTH CHECKS RESTARTS CREATED ede4b9e2 app 4 gru run running (replica) 3 total, 3 passing 0 2h29m ago cc6ceb2b app 4 iad run running (replica) 3 total, 3 passing 0 2h30m ago a192ee2e app 4 iad run running (leader) 3 total, 3 passing 0 2h31m ago
On the board we see that the replication delay increases all the time.
I scale the vm-size and have the same behaviour.
Could you help us understand what happens?
