* Excessive spillage in the Query Profile indicates that intermediate query results are being written to remote storage (disk) instead of being processed in memory. This usually happens when:
* The virtual warehouse does not have sufficient resources (e.g., memory, compute power).
* Large datasets or complex operations (e.g., joins, aggregations) require more memory than available.
Solution:
* Increase the size of the virtual warehouse to provide more compute and memory resources.
Why Other Options Are Incorrect:
* A. Poor query optimization: This could contribute, but spillage is primarily tied to resource constraints.
* B. Expired temporary tables: Temporary tables have no relation to spillage.
* D. Improper CTEs: The use of CTEs does not directly cause spillage.

Explanation
Cloned objects are replicated physically rather than logically to secondary databases. That is, cloned tables in a standard database do not contribute to the overall data storage unless or until DML operations on the clone add to or modify existing data. However, when a cloned table is replicated to a secondary database, the physical data is also replicated, increasing the data storage usage for your account.

Organizing files into logical paths can significantly improve the efficiency of data loading from an external stage. This practice helps in managing and locating files easily, which can be particularly beneficial when dealing with large datasets or complex directory structures1.
