How does this compare against Temporal/Cadence/Conductor? Does hatchet also support durable execution?

It's very similar - I used Temporal at a previous company to run a couple million workflows per month. The gRPC networking with workers is the most similar component, I especially liked that I only had to worry about an http2 connection with mTLS instead of a different broker protocol.

Temporal is a powerful system but we were getting to the point where it took a full-time engineer to build an observability layer around Temporal. Integrating workflows in an intuitive way with OpenTelemetry and logging was surprisingly non-arbitrary. We wanted to build more of a Vercel-like experience for managing workflows.

We have a section on the docs page for durable execution [1], also see the comment on HN [2]. Like I mention in that comment, we still have a long way to go before users can write a full workflow in code in the same style as a Temporal workflow, users either define the execution path ahead of time or invoke a child workflow from an existing workflow. This is also something that requires customization for each SDK - like Temporal's custom asyncio event loop in their Python SDK [3]. We don't want to roll this out until we can be sure about compatibility with the way most people write their functions.

We did it in like 5 minutes by adding in otel traces? And maybe another 15 to add their grafana dashboard?

What obstacles did you experience here?
