With default settings, how long will a query run on snowflake

A. Snowflake will cancel the query if it runs more than 48 hours

B. Snowflake will cancel the query if it runs more than 24 hours

C. Snowflake will cancel the query if the warehouse runs out of memory

D. Snowflake will cancel the query if the warehouse runs out of memory and hard disk storage

Answer: D

Explanation:

In Snowflake, the duration that a query will run before it is automatically canceled depends on the timeout settings of the virtual warehouse executing the query. By default, Snowflake does not have a fixed timeout for queries based on execution time alone. Instead, queries are subject to resource limitations.

Here are the options reviewed:

A. Snowflake will cancel the query if it runs more than 48 hours

Snowflake does not have a default 48-hour timeout setting for queries.

B. Snowflake will cancel the query if it runs more than 24 hours

Similarly, Snowflake does not have a default 24-hour timeout setting for queries.

C. Snowflake will cancel the query if the warehouse runs out of memory

Snowflake’s virtual warehouses are designed to scale automatically or can be resized manually to provide more compute resources if needed. However, if the warehouse is unable to acquire additional memory and the query exceeds the memory available to the warehouse, the query may be canceled due to resource limitations.

D. Snowflake will cancel the query if the warehouse runs out of memory and hard disk storage

This is the correct option. Snowflake operates on a shared-nothing architecture, where each virtual warehouse has its own compute resources, including memory and temporary disk storage. If a query consumes all available memory and disk resources, it will be canceled. Snowflake manages storage resources across its services, and if a query exceeds the resources available to it, the query will be terminated.

So, the most accurate answer is:

D. Snowflake will cancel the query if the warehouse runs out of memory and hard disk storage.
