Google Cloud Professional Data Engineer PDE — Topic 1 Question 282

Question

You are using a Dataflow streaming job to read messages from a message bus that does not support exactly-once delivery. Your job then applies some transformations, and loads the result into BigQuery. You want to ensure that your data is being streamed into BigQuery with exactly-once delivery semantics. You expect your ingestion throughput into BigQuery to be about 1.5 GB per second. What should you do?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Use the BigQuery Storage Write API and ensure that your target BigQuery table is multiregional. BigQuery is a serverless, petabyte-scale data warehouse for fast SQL analytics with no infrastructure to manage. This option meets the real-time / low-latency performance requirement.
