How should you design the data ingestion?

A. Vehicles write data directly to GCS
B. Vehicles write data directly to Google Cloud Pub/Sub

C. Vehicles stream data directly to Google BigQuery

D. Vehicles continue to write data using the existing system (FTP)

Explanation:
Streamed data is available for real-time analysis within a few seconds of the first streaming insertion into a table.

Instead of using a job to load data into BigQuery, you can choose to stream your data into BigQuery one record at a time by using the tabledata().insertAll() method. This approach enables querying data without the delay of running a load job.
