Question 530
A data engineering team validates the full streaming-to-lakehouse pipeline. The current environment exhibits the following problem: a streaming pipeline's operational alert says green but source freshness has stopped. Which corrective action addresses the root cause?
Explanation
Correct Answer
Monitor event-time freshness and source lag in addition to job status. A running query can be healthy technically while delivering stale business data.
Incorrect Answers
The team measures only successful Eventstream input but not destination failures. End-to-end delivery metrics expose downstream loss.
A Delta target is updated with duplicate replay records. Exactly-once business effects need replay-safe output.
An Eventhouse time-window query counts processing-time buckets rather than event timestamps. Processing delays must not silently move facts between business periods.
