Greetings.
Right, wrong, or indifferent I have an AG for a large Data Warehouse environment. Every night about 4500 ETL jobs do their thing. About two hours in to the ETL jobs tonight I needed to reboot the Secondary node. Now I did this knowing my main DB would then be In Recovery for a while after that, but was thinking along the lines of a couple hours. Based on what I'm seeing in my log file, I'm looking at 60 hours until this guy recovers.
What I do have in my favor (by pure luck) is a LOT of room for the Log to grow (> 1TB). Also around 9AM most of these jobs will stop running, so things should speed up.
Obviously if I didn't have gobs of free space laying around my options would be less. Out of curiosity though, would there be any benefit to just dropping the Secondary from the AG and then re-adding it after the ETL jobs re finished?
Thanks!
Thanks in advance! ChrisRDBA
