Retry and risk#

This activity is safe to retry: running it again after a transient failure does not repeat a side effect. If a run is interrupted and the outcome of a step is unknown, the step is never retried automatically (what to do). How activities declare this: characteristics, retries and risk.

Every activity also has the engine's common properties: Timeout and Continue On Error.
