I'll do it on Monday, it's quite simple.

Please coordinate with me before doing this. The views need to be recreated

Sure. I have recreated views before (with depool too)

@Ladsgroup has the schema change already been applied to production? Or is it just the views that were updated

Both are done.

Cool, thanks (just wondering since I'm used to notes about host by host progress)

Yeah, it's a small table with not that much reads nor writes so I could run the alter on master with replication and in the cloud, I ran maintain-views live.
