Hi
looks like there is nothing we can do in order to enforce Zero downtime for our GCP Cloud SQL during maintenance window.
from what i've read seems like even adding Failover replicas will not help here as the replicas will have the same maintenance window, meaning they will both get down during maintenance.
also i assume read replicas also wont help here as read replicas are not ment for failover, although they have a different maintenance window (which can be anytime).
am i missing something?
thanks
