Replay runs in bulk

After fixing an incident, replay the affected runs by function, time range, and status. Replay creates new executions, so check which charges, messages, or records could repeat. Follow Idempotency when a repeated charge, message, or record update would cause harm.

1. Deploy and verify the fix.
2. Open the function in the dashboard and choose Replay from All actions.
3. Name the replay after the incident. Select its time range and the statuses to include.
4. Review the selection. Include successful runs only if they also need recovery.
5. Start the replay and watch its progress. Replay spreads the selected work over time. Use a narrow time window and confirm the affected functions before starting. For one run, use Rerun a run instead. For events skipped while a function was paused, select the Skipped status after resuming that function. Historical availability follows your plan's event retention; check pricing rather than assuming an unlimited replay window.
