Google Cloud Professional Data Engineer PDE — Topic 1 Question 100

Question

You have a requirement to insert minute-resolution data from 50,000 sensors into a BigQuery table. You expect significant growth in data volume and need the data to be available within 1 minute of ingestion for real-time analysis of aggregated trends. What should you do?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Use a Cloud Dataflow pipeline to stream data into the BigQuery table. BigQuery is a serverless, petabyte-scale data warehouse for fast SQL analytics with no infrastructure to manage. Dataflow runs serverless Apache Beam pipelines for stream and batch data processing with autoscaling. This option meets the real-time / low-latency performance requirement.
