Hello,
I have implemented an AlwaysOn Read_scale, but still have a question and I can't find answer anywhere.
If I did a failover and now my secondary server works as a primary, and after some period of time I can bring my real primary to life, so how long I must keep it as a secondary? I mean, How long it will take to transfer all data that have been collected during downtime, from new_primary to my real primary?
