You need to load a dataset with multiple terabytes of clickstream data into BigQuery. The data arrives each day as compressed JSON files in a Cloud Storage bucket. You need a low-cost, programmatic, and scalable solution to load the data into BigQuery. What should you do?
A
Create an external table in BigQuery pointing to the Cloud Storage bucket and run the INSERT INTO ... SELECT * FROM external_table command.
B
Use the BigQuery Data Transfer Service from Cloud Storage.
C
Create a Cloud Run function to run a Python script to read and parse each JSON file, and use the BigQuery streaming insert API.
D
Use Cloud Data Fusion to create a pipeline to load the JSON files into BigQuery.
