Question 320
A scheduled Fabric load needs safe control-table state. The current environment exhibits the following problem: a source timestamp is nonunique and changes on multiple records at once. Which corrective action addresses the root cause?
Explanation
Correct Answer
Use a tie-breaker or CDC sequence alongside watermark state. Timestamp equality must not cause missing updates.
Incorrect Answers
A load replays a successful batch after a network error. Uncertain acknowledgments require safe retries.
Two instances of the same incremental job run concurrently. Uncoordinated writers can corrupt state or advance checkpoints incorrectly.
A failed batch advances its high-watermark and drops unprocessed rows. A checkpoint must represent successfully published data.
