Yeah, this is pretty much exactly how we propose its done (restate services are inherently versioned, you can register new code as a new version and old invocations will go to the old version). The only caveat being that we generally recommend that you keep it to just a few minutes, and use delayed calls and our state primitives to have effects that span longer than that. Eg, to poll repeatedly a handler can delayed-call itself over and over, and to wait for a human, we have awakeables (https://docs.restate.dev/develop/ts/awakeables/ https://docs.restate.dev/develop/ts/awakeables/) More discussion: https://restate.dev/blog/code-that-sleeps-for-a-month/ https://restate.dev/blog/code-that-sleeps-for-a-month/
