Be Apple, innovate, give us second iPhone moment so you wouldn't worry so much about revenue drop in services. Or make payment via Apple so good, your customers would go for it even with price difference. Just stop stupid, monopolistic tactics.
Ok, but most of the time you would like to test that change on a copy or almost up to date replica, to see measure things like how long it does take. If you were copying the data, with things like PII filtering, to the branch development database and allow folks to test it there it would be even more amazing. Great start tho!
Aren't schema changes are actually a big problem when there is a huge amount of data in the table. Adding a column / index to a table that has 500M rows in it is usually the pita. This is definitely something on the right direction, but would love to see this supporting this with the data itself.
