> It'd be an interesting experiment to take memory snapshots after each step in a workflow, which an API like Firecracker might support...I think some durable execution engines have experimented with this type of system before, but I can't find a source now - perhaps someone has a link

Trigger.dev currently uses CRIU, but I recall reading on HN (https://news.ycombinator.com/item?id=45251132) that they're moving to MicroVMs. Their website (https://feedback.trigger.dev/p/make-runs-startresume-faster-...) suggests that they're using Firecracker specifically, but I haven't seen anything beyond that. It would definitely be interesting to hear how it works out, because I'm not aware of another Durable Execution platform that has done this yet.
