Create a mapping to write data to Google BigQuery. Use the Google BigQuery connection, and define the write operation properties to write data to Google BigQuery.
You can perform insert, update, delete, and upsert operations on a Google BigQuery target.
To perform a update, delete, or upsert operation, you must add an Update Strategy transformation to a mapping and flag the records in an update strategy expression.
When you run a mapping on the Spark engine, you cannot add an Update Strategy transformation. Hence, you cannot perform update, delete, or upsert operations on a Google BigQuery target when you run a mapping on the Spark engine.
For more information about configuring an Update Strategy transformation, see "Update Strategy Transformation" in the
