Deploy instantly with ALGORITHM=INSTANT
deploy requests
// what it does
--instant applies eligible changes (like adding a column) using MySQL's built-in ALGORITHM=INSTANT, skipping the shadow-table copy — the deploy completes in seconds regardless of table size.
// shell
$ pscale deploy-request deploy mydb 12 --instant// gotcha
The trade: an instant deploy CANNOT be reverted — there's no shadow copy to fall back to. Use it for low-risk additive changes only; anything you might want to undo goes through the normal path.
