Mapping task with Oracle CDC sources use case

Your organization needs to replicate real-time changed data from a mission-critical Oracle production system to minimize intrusive, non-critical work, such as offline reporting or analytical operations system.
Use Google BigQuery V2 Connector to capture changed data from the Oracle CDC source and write the changed data to an Google BigQuery target table. Add the Oracle CDC sources in mappings, and then run the associated mapping tasks to write the changed data to the target.
