Follower clusters are a ScaleGrid feature that allows you to keep two independent database systems (of the same type) in sync. Here are a few critical ways in which it differs from replication: You can control how frequently the destination system syncs from source – once a week, once a day, or even less frequently. This helps reduce the load on the source system. Since they are two independent systems, you have much more flexibility over the data that is synced.
