@@ -534,6 +534,12 @@ As noted in the comment, `ecStep` does not equal `ecJob`. They are two different
`ExecutionContexts`. The one scoped to the `Step` is saved at every commit point in the
`Step`, whereas the one scoped to the Job is saved in between every `Step` execution.
NOTE: In the `ExecutionContext`, all non-transient entries must be `Serializable`.
Proper serialization of the execution context underpins the restart capability of steps and jobs.
Should you use keys or values that are not natively serializable, you are required to
employ a tailored serialization approach. Failing to serialize the execution context
may jeopardize the state persistence process, making failed jobs impossible to recover properly.
