PowerExchange for Google BigQuery Connections

PowerExchange for Google BigQuery Connections

When you configure a Google BigQuery connection, you define the connection attributes that the PowerCenter Integration Service uses to connect to the Google BigQuery database.
The following table describes the Google BigQuery connection properties:
Property
Description
Service Account ID
Specifies the client_email value present in the JSON file that you download after you create a service account.
Service Account Key
Specifies the private_key value present in the JSON file that you download after you create a service account.
Connection mode
The mode that you want to use to read data from or write data to Google BigQuery.
Select one of the following connection modes:
  • Simple. Flattens each field within the Record data type field as a separate field in the mapping.
  • Hybrid. Displays all the top-level fields in the Google BigQuery table including Record data type fields. PowerExchange for Google BigQuery displays the top-level Record data type field as a single field of the String data type in the mapping.
  • Complex. Displays all the columns in the Google BigQuery table as a single field of the String data type in the mapping.
Default is Simple.
Schema Definition File Path

If you have created multiple projects with the same service account, enter the ID of the project that contains the dataset that you want to connect to.
