Google Associate Data Practitioner Exam - Topic 3 Question 9 Discussion

Your organization has a petabyte of application logs stored as Parquet files in Cloud Storage. You need to quickly perform a one-time SQL-based analysis of the files and join them to data that already resides in BigQuery. What should you do?
C) Create external tables over the files in Cloud Storage, and perform SQL joins to tables in BigQuery to analyze the data.
A) Create a Dataproc cluster, and write a PySpark job to join the data from BigQuery to the files in Cloud Storage.
B) Launch a Cloud Data Fusion environment, use plugins to connect to BigQuery and Cloud Storage, and use the SQL join operation to analyze the data.
D) Use the bq load command to load the Parquet files into BigQuery, and perform SQL joins to analyze the data.

[All Associate Data Practitioner Questions]

Your organization has a petabyte of application logs stored as Parquet files in Cloud Storage. You need to quickly perform a one-time SQL-based analysis of the files and join them to data that already resides in BigQuery. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: C

Creating external tables over the Parquet files in Cloud Storage allows you to perform SQL-based analysis and joins with data already in BigQuery without needing to load the files into BigQuery. This approach is efficient for a one-time analysis as it avoids the time and cost associated with loading large volumes of data into BigQuery. External tables provide seamless integration with Cloud Storage, enabling quick and cost-effective analysis of data stored in Parquet format.

Wait, can you really do SQL joins with external tables? Sounds too good to be true!

I recall that Cloud Data Fusion is useful for ETL processes, but for a quick SQL analysis, I wonder if option C is still the best approach.

I practiced a question similar to this, and I feel like using the bq load command in option D might be overkill for a one-time analysis.

I think option C sounds familiar; creating external tables over the Parquet files seems like a straightforward way to analyze them without moving data.

For a petabyte-scale dataset, I'd be hesitant to use the bq load command (option D). That could take a really long time to ingest all the data. I'm inclined to go with option C and create the external tables in BigQuery. Seems like the most efficient way to get the job done.

Option B with Cloud Data Fusion looks interesting, but I'm not as familiar with that service. I think I'll stick with the more traditional BigQuery approach and go with option C. The external table integration should be pretty straightforward.

I'm a bit unsure about this one. The question mentions a "one-time" analysis, so I'm not sure if creating a Dataproc cluster for a PySpark job is the best use of resources. I'm leaning towards option C or D, but I'll need to think it through a bit more.

This seems like a straightforward data integration task, so I'll likely go with option C. Creating external tables in BigQuery to join the Parquet files from Cloud Storage seems like the most efficient approach.
