Snowflake Exam ARA-C01 Topic 6 Question 24 Discussion

Actual exam question for Snowflake's ARA-C01 exam
Question #: 24
Topic #: 6
[All ARA-C01 Questions]

A company has built a data pipeline using Snowpipe to ingest files from an Amazon S3 bucket. Snowpipe is configured to load data into staging database tables. Then a task runs to load the data from the staging database tables into the reporting database tables.

The company is satisfied with the availability of the data in the reporting database tables, but the reporting tables are not pruning effectively. Currently, a size 4X-Large virtual warehouse is being used to query all of the tables in the reporting database.

What step can be taken to improve the pruning of the reporting tables?

Show Suggested Answer Hide Answer
Suggested Answer: C

Effective pruning in Snowflake relies on the organization of data within micro-partitions. By using an ORDER BY clause with clustering keys when loading data into the reporting tables, Snowflake can better organize the data within micro-partitions. This organization allows Snowflake to skip over irrelevant micro-partitions during a query, thus improving query performance and reducing the amount of data scanned12.

* Community article on recognizing unsatisfactory pruning and improving it1

True, Option A sounds inefficient. I agree, Option C seems practical.

Eliminating Snowpipe (Option A) seems extreme and not related to pruning.

C makes sense. OPTIMIZE and ORDER BY can make data more accessible and improve performance.

I'm leaning towards option C. Using ORDER BY might help with pruning.

It's one option. Another is to increase the size of the virtual warehouse to a size 5X-Large.

We can eliminate the use of Snowpipe and load the files into internal stages using PUT commands.
