Datastream adds MongoDB extended JSON canonical mode for BigQuery streams
Google Cloud Datastream now supports MongoDB extended JSON canonical mode as the default format for new streams from MongoDB sources to BigQuery. This enhancement ensures higher data fidelity by explicitly labeling every BSON type. It prevents precision loss during data exchange, benefiting users migrating or replicating MongoDB data to BigQuery.
