Google Cloud Storage Connector for CData Sync

Overview

The CData Sync App provides a straightforward way to continuously pipeline your Google Cloud Storage data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.

The GoogleCloudStorageDestination connector can be used from the CData Sync application to pull data from GoogleCloudStorageDestination and move it to any of the supported destinations.

Google Cloud Storage Connector for CData Sync

Establishing a Connection

Create a connection to GoogleCloudStorageDestination by navigating to the Connections page in the Sync App application and selecting the corresponding icon in the Add Connections panel. If the GoogleCloudStorageDestination icon is not available, click the Add More icon to download and install the GoogleCloudStorageDestination connector from the CData site.

Required properties are listed under the Settings tab. The Advanced tab lists connection properties that are not typically required.

OAuth

Use the OAuth authentication standard to connect to GoogleCloudStorageDestination. You can authenticate with a user account or with a service account. A service account is required to grant organization-wide access scopes to the Sync App. The Sync App facilitates these authentication flows as described below.

User Accounts

See Using OAuth Authentication for an authentication guide. In this OAuth flow, you can connect without setting any connection properties for your user credentials. Click Connect and the Sync App opens the GoogleCloudStorageDestination OAuth endpoint. Log in and grant permissions to the Sync App. The Sync App then completes the OAuth process.

Service Accounts

Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the Sync App.

You need to create an OAuth application in this flow. See Creating a Custom OAuth App to create and authorize an app. You can then connect to GoogleCloudStorageDestination data that the service account has permission to access.

After setting the following connection properties, you are ready to connect:

  • OAuthJWTCertType: Set this to "PFXFILE".
  • OAuthJWTCert: Set this to the path to the .p12 file you generated.
  • OAuthJWTCertPassword: Set this to the password of the .p12 file.
  • OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
  • OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
  • OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
  • ProjectId: Set this to the Id of the project you want to connect to.
When you connect the Sync App completes the OAuth flow for a service account.

You will also need to specify the following property:

  1. Path: The path where the data will be replicated to. For example: /{bucket}/{directory}/. Bucket is required and must be supplied in the path. Directory is not. If the directory within the bucket is not specified, sync will create a folder in the root folder to represent the table being replicated.

PseudoColumns

This property indicates whether or not to include pseudo columns as columns to the table.

Remarks

This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".

Timeout

The value in seconds until the timeout error is thrown, canceling the operation.

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the Sync App throws an exception.

UserDefinedViews

A filepath pointing to the JSON configuration file containing your custom views.

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The Sync App automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the Sync App.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
	"MyView": {
		"query": "SELECT * FROM NorthwindOData WHERE MyColumn = 'value'"
	},
	"MyView2": {
		"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
	}
}
Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:
"UserDefinedViews", "C:\\Users\\yourusername\\Desktop\\tmp\\UserDefinedViews.json"
