Then rolling forwards and backwards is a whole deployment away, or mucking about with infrastructure, vs tweaking a percentage flag somewhere. If you want to get fancy with changes (and I've seen it done) you have something else capable of controlling that percentage setting that is tied in to your monitoring. Start out low, say 1% of requests hitting the new path. Automatically ramp up over time to full 100%. If you see failures, automatically drop back to 0% until it can be ascertained that the failure didn't come from the new code. |
