Currently, the importer causes a long spike once per day, I propose that we change it to several shorter spikes. Hourly seems like a good compromise. Or maybe 15 minutes?

Replication frequency is set to 1 hour on the maps-test cluster. We can see that the server load average and IO peaks every hour and barely has time to go back down before the next replication. We can also see that postgresql replication often lags by > 10 minutes. I have no idea what the cause of that is at the moment, but it looks like something that needs to be fixed before we enable that on production servers.
Tilerator notification is failing regularly on the maps-test cluster, which it the cluster where hourly updates are enabled. This is correlation, not causality, still, we should make sure the problem isn't related (my suspicion: it is actually related).
@Gehel Are both of these still the case? (I found a Grafana dashboard for the production cluster, but not the maps-test cluster.)
Edit: Of course I found the control to switch to maps-test two seconds after posting...
