Durable execution helps AI agents survive failures
is a way to keep long-running code from losing progress when a server fails or a temporary error happens. is presented as a main tool for this idea. The overall process is handled as a workflow, real work or outside service calls are split into , and event history records what has already happened.
Restate is also included as another source for the same concept. The core idea is to make long tasks easier to resume and to avoid repeating steps that already finished.
Key points
- helps long tasks continue after failures.
- organizes work into a workflow, , and event history.
- Restate is another for concepts.
- can waste fewer tokens when completed steps are reused instead of repeated.
- The cost benefit depends on careful design, not on the tool alone.
