Question 570
A finance engineering team defines service-level objectives for data availability. The current environment exhibits the following problem: operations cannot distinguish a late-but-correct batch from a failed batch. What is the best engineering response?
Explanation
Correct Answer
Record both completion state and business-window watermark. SLA indicators need event-time coverage as well as run status.
Incorrect Answers
A daily fact load has expected row count but duplicate business keys. Cardinality alone cannot establish data validity.
A CDC load silently skips deleted records. Change correctness requires detecting missing and obsolete records.
Leadership measures only pipeline success but key data arrives three hours late. Technical success can coexist with missed business SLAs.
