Read replicas come with their own complexity as you have to account for the lag time on the replica for UX. This leads to a lot of unexpected quirks if it’s not planned for.


That's true, but you can use your replica only for non-realtime reporting, or even just as a hot standby.

Edit: Careful for the non-realtime reporting though if you want to run very slow queries - those will pause replication and can be a PITA.


A hot standby / failover still meets this definition. That’s how I interpreted what was being described.
