A query is using more credits than expected. The Query Profile shows that a majority of the query execution is spent on remote disk I/O. How can this be prevented in the future?
Correct Answer: B
* If a query spends most of its time on remote disk I/O, it indicates that the virtual warehouse does not have enough compute resources to handle the workload efficiently. Increasing the size of the virtual warehouse (e.g., from X-Small to Medium) provides more CPU and memory, reducing disk I/O and improving performance. Why Other Options Are Incorrect: * A. Convert to Maximized mode: Snowflake does not have a "Maximized mode" for warehouses. * C. Increase auto-suspend time: This affects cost efficiency but does not optimize disk I/O. * D. Increase the number of clusters: Adding clusters is for concurrency, not reducing disk I/O. References: * Optimizing Query Performance
