Discuss Snowflake ARA-R01 Exam Topic 4 Question 46

Which of the below commands will use warehouse credits?

ASHOW TABLES LIKE 'SNOWFL%';

BSELECT MAX(FLAKE_ID) FROM SNOWFLAKE;

CSELECT COUNT(*) FROM SNOWFLAKE;

DSELECT COUNT(FLAKE_ID) FROM SNOWFLAKE GROUP BY FLAKE_ID;

Suggested Answer: B, C, D

Warehouse credits are used to pay for the processing time used by each virtual warehouse in Snowflake. A virtual warehouse is a cluster of compute resources that enables executing queries, loading data, and performing other DML operations.Warehouse credits are charged based on the number of virtual warehouses you use, how long they run, and their size1.

Among the commands listed in the question, the following ones will use warehouse credits:

SELECT MAX(FLAKE_ID) FROM SNOWFLAKE: This command will use warehouse credits because it is a query that requires a virtual warehouse to execute.The query will scan the SNOWFLAKE table and return the maximum value of the FLAKE_ID column2. Therefore, option B is correct.

SELECT COUNT(*) FROM SNOWFLAKE: This command will also use warehouse credits because it is a query that requires a virtual warehouse to execute.The query will scan the SNOWFLAKE table and return the number of rows in the table3. Therefore, option C is correct.

SELECT COUNT(FLAKE_ID) FROM SNOWFLAKE GROUP BY FLAKE_ID: This command will also use warehouse credits because it is a query that requires a virtual warehouse to execute.The query will scan the SNOWFLAKE table and return the number of rows for each distinct value of the FLAKE_ID column4. Therefore, option D is correct.

The command that will not use warehouse credits is:

SHOW TABLES LIKE 'SNOWFL%': This command will not use warehouse credits because it is a metadata operation that does not require a virtual warehouse to execute.The command will return the names of the tables that match the pattern 'SNOWFL%' in the current database and schema5. Therefore, option A is incorrect.

A is just showing tables, no credits used.

True, but I feel B is the most intensive.

What about D? Grouping can be costly too.

I agree, B uses more resources.

I think it's B. It seems like a heavy query.

Wait, are you sure about that? I thought all selects cost credits!

Nope, B) doesn't use credits, just reads data.

D) SELECT COUNT(FLAKE_ID) might use credits, but I'm not sure.

I thought SHOW TABLES was a free command, but I could be mixing it up with other SQL commands.

Shaunna 3 months ago

I feel like the GROUP BY command might use more resources, so it could be the one that uses warehouse credits.

Felix 3 months ago

I remember practicing a question about counting rows, but I can't recall if that always uses credits.

Pamella 3 months ago

I think commands that involve querying data usually use warehouse credits, but I'm not sure which one it is here.

Derick 3 months ago

I think it might be option D, but I need to double-check if GROUP BY affects credit usage.

Annita 4 months ago

I’m a bit confused; I thought SHOW commands didn’t use credits, but I’m not completely certain.

Jettie 4 months ago

I remember practicing similar questions, and I feel like SELECT statements generally consume credits.

Germaine 5 months ago

I think commands that query data usually use credits, but I'm not entirely sure which one it is here.
