• D. Anytime you see words like “develop” or “manually” be suspicious given this is cloud and everything is supposed to be automated and point-and-click easy. Eliminate A. Federated queries are SQL queries initiated FROM BigQuery to Cloud Spanner or Cloud SQL databases. So B doesn’t make sense. The Database Migration Service does not support BigQuery as a destination database engine. Eliminate C. That leaves D. From Google’s documentation, “Datastream is a serverless and easy-to-use Change Data Capture (CDC) and replication service that allows you to synchronize data across heterogeneous databases, storage systems, and applications reliably and with minimal latency. Datastream supports change data streaming from Oracle and MySQL databases to Google Cloud Storage (GCS). The service offers streamlined integration with Dataflow templates to power up to date materialized views in BigQuery for analytics, replicate their databases into Cloud SQL or Cloud Spanner for database synchronization, or leverage the event stream directly from GCS to realize event-driven architectures.”
