Thank you for saving me from the heartbreak of finding this out later. Seriously you just saved me a ton of time.

So even in a huge pile of mail, everything would have to be reprocessed. Since it's so rare, I'm definitely going to set up metrics to monitor when it does happen.
Do you have any insight on how people store the mail? Do they actually use the UID to reference it or is it used as more of a cursor?
- ts4z 7y agoMost clients want to use UID, and it’s a good key for the same reason a SQL row number is, and inconvenient for servers for the same reason consistent hashing schemes don’t have it. I’m not sure what you mean about a cursor. I’m sure clients use UIDs as cursors. They’re good for that.
