Long-Running Workflows

Example: "Email me every morning for a week."

The Sleep Node

You need a persisted database (Postgres).

1. Node executes.
2. Next step: "Wait 24 hours."
3. System saves state to DB, kills process.
4. Cron job wakes up 24 hours later, loads state, resumes execution.

Without persistence, you cannot build long-running agents.
