Run schema, record-count, and sensitive-data checks against the same dataset.
The checks are independent; publish only after all three succeed.
Which configuration is most appropriate?
Use a Step Functions Parallel state for fixed independent branches and continue after all branches complete.
Detailed explanation
This reduces isolation and makes individual retries harder; one failure affects all checks.

Parallel runs independent branches at the same time and transitions after every branch finishes.

- Confirm current AWS service behavior in the official DEA-C01 documentation.
Foundation review
Parallel versus Map
Parallel represents known branch types; Map repeats work over a variable collection.
Failure propagation
Decide whether one failed check stops publication or becomes a recorded warning.
