> I haven't used Kamal yet but how does it deal with your action cable process and background worker becoming healthy with v2 of your app while the web app is still serving v1 of your code or vice versa? Isn't this the same problem you'd have deploying your updated code to any number of servers larger than one? There's no way to shift over all the traffic at the exact same time, so all database changes have to be forwards compatible e.g. you can add columns before using them, all code changes have to be cross compatible (e.g. if there are unknown job names or arguments, they get automatically retried)
