I wonder how this compares, conceptually, to Temporal? While Temporal doesn't talk about a single centralized log, I feel the output is the same: your event handlers become durable and can be retried without re-executing certain actions with outside systems. Both Restate and Temporal feel, as a developer coding these event handlers, like a framework where they handle a lot of the "has this action been performed yet?" and such for you.

Though to be fair I've only read Temporal docs, and this Restate blog post, without much experience in either. Temporal may not have as much on the distributed locking (or concept of) side of things that Restate does, in this post.

Temporal is related, but I would say it is a subset of this.

If you only consider appending results of steps of a handler, then you have something like Temporal.

This here uses the log also for RPC between services, for state that outlives an individual handler execution (state that outlives a workflow, in Temporal's terms).

That makes a lot of sense, thank you! Extending out to other operations and not just event handlers/workflows would be neat.
