Your team develops services that run on Google Cloud. You want to process messages sent to a Pub/Sub topic, and then store them.

  • A. Process the messages with a Dataproc job, and write the output to storage.
  • B. Process the messages with a Dataflow streaming pipeline using Apache Beam's PubSubIO package, and write the output to storage.
  • C. Process the messages with a Cloud Function, and write the results to a BigQuery location where you can run a job to deduplicate the data.
  • D. Retrieve the messages with a Dataflow streaming pipeline, store them in Cloud Bigtable, and use another Dataflow streaming pipeline to deduplicate messages.
