Elastic mapping use case

You work for an organization that stores large amount of purchase order details, such as customer ID, item codes, and item quantity in Google Cloud Storage. You need to port the data from Google Cloud Storage to another cloud-based environment to quickly analyze the purchase order details and to increase future revenues.
Use Google BigQuery V2 Connector to create an elastic mapping that runs on the elastic cluster to achieve faster performance when you read all the purchase records from Google Cloud Storage and write the records to a Google BigQuery target.
