Question 590
An engineer monitors Warehouse performance after a new ETL release. The current environment exhibits the following problem: a slow query appears only during capacity saturation. Which option directly handles this observed condition?
Explanation
Correct Answer
Correlate the run timestamp with capacity utilization and competing workloads. Shared capacity load can amplify query latency.
Incorrect Answers
A warehouse model refresh isn't seeing newly committed rows. Query availability and consumer refresh can have different timing.
T-SQL queries run much slower after new tables were loaded. Plan and data distribution changes affect Warehouse performance.
A pipeline copies millions of rows but the target table is short. Merge filters and mismatched keys can drop intended changes.
