The point is that you can write code instead of JSON/YAML like traditional microservice orchestration like AWS step functions. And it’s not a limited dsl—you have the full lang at your disposal, with the one requirement that deterministic code (workflows / the durable code) is in separate functions from non deterministic code (like making a network request, called “Activities”).
Not trying to argue. Genuinely curious if you think this is within the realm of "not take anything special into account" (be forced to use a specific SDK and lay your logic out in the exact way it supports) or if you didn't know this was referring to Temporal?
I thought this comment chain was about durable execution in general. Temporal seems to be that plus some RPC stuff that is a lot more than "nothing special."
All the durable execution systems have to run your code in certain way that persists steps like RPCs (and need to provide a mechanism for you to tell the system which functions have RPCs) so they can recover in case of process failures. They all also happen to provide common orchestrator features like retries and timeouts because devs find it useful.
