DBCC CLONEDATABASE is Semi-Discontinued

Voice of the DBA

I saw a tweet that DBCC CLONEDATABASE was being discontinued for production databases, which both scared me and didn't make sense. I've used this a few times for a quick copy of a database and like how it works. Discontinuing it seemed strange to me.

Then I read the blog post, which notes that it's not being supported for production deployments. The post doesn't explain why, but I'm guessing this is because all the stats and other metadata moves, and this might mess up the optimizer if different data is added. I don't know who deploys production databases like this, but I could see people who have federated or sharded databases using this to create a new blank copy and then uploading data into it. Or maybe people who need new databases that are distributed onto remote office/edge devices used it? If you use this to create production dbs, let me know.
