Replicate Multiple Google Cloud Storage Accounts

CData Sync is a standalone application designed to support a variety of replication scenarios, such as replicating both sandbox and production instances into your database. It includes a web-based interface that simplifies the management of multiple Google Cloud Storage connections. In this article, we demonstrate how to use the web app to replicate multiple Google Cloud Storage accounts into a single database.

Configure Replication Destinations

Using CData Sync, you can replicate data from Google Cloud Storage to any number of databases, both cloud-based and on-premises. In this example, we use SQLite as the replication destination to demonstrate the process. To add it as a destination, navigate to the Connections tab.

For each destination database:

1. Click Add Connection.
2. Select the Destinations tab and locate the SQLite connector.
3. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the SQLite connector. For more information about installing new connectors, see Connections in the Help documentation.
4. To connect to SQLite, set the following connection properties:
   • Connection Name: Enter a connection name of your choice.
   • Data Source: Enter the path to the database. You can replicate to an existing database or to a new one. The application must have permission to access the database.

5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to SQLite and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

Configure the Google Cloud Storage Connection

You can configure a connection to Google Cloud Storage from the Connections tab. To add a connection to your Google Cloud Storage account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (Google Cloud Storage).
3. Configure the connection properties.
   
   

   The Google Cloud Storage source connector supports OAuth, OAuth PKCE, OAuth JWT, and GCP Instance Account authentication.

   OAuth (User Account)

   To connect with OAuth custom credentials, set the following properties:

   • Auth Scheme: Select OAuth.
   • OAuth Version: Select the version of OAuth you want to use. The default version is 2.0.
   • (Optional) Scope: Specify the scope of your access to the application.
   • (Optional) OAuth Authorization URL, OAuth Access Token URL, OAuth Refresh Token URL: Override the default endpoints if needed.

   When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth flow completes.

   OAuth JWT (Service Account)

   For silent authentication or delegated organization-wide access, create a service account in Google Cloud, grant it the required permissions on your bucket or project, register a custom OAuth application, and download the certificate file (.p12 or .pfx). Then set:

   • Auth Scheme: Select OAuthJWT.
   • OAuth JWT Cert: Path to your JWT certificate store.
   • OAuth JWT Cert Type: Type of key store. The default is PEMKEY_BLOB.
   • OAuth Client Id and OAuth Client Secret: Values from your registered OAuth application.
   • (Optional) OAuth JWT Cert Password, OAuth JWT Cert Subject, OAuth JWT Subject, OAuth JWT Subject Type, OAuth JWT Public Key Id: For delegated access and certificate configuration.

   For OAuth PKCE and GCP Instance Account methods, refer to the Help documentation.

   
4. Click Connect to Google Cloud Storage to ensure that the connection is configured properly.
5. Click Save & Test to save the changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of Google Cloud Storage tables you wish to replicate into SQLite, and click Add Tasks again.

Customize Your Replication

You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication with the help of SQL queries.

The statement below caches and incrementally updates a table of Google Cloud Storage data:

REPLICATE Buckets;

You can specify a file containing the replication queries you want to use to update a particular database. Separate the replication statements with semicolons. The following options are useful when replicating multiple Google Cloud Storage accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_Buckets SELECT * FROM Buckets;
  

• Alternatively, use a different schema:

  REPLICATE PROD.Buckets SELECT * FROM Buckets;
  

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at specified intervals, ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Google Cloud Storage data to disparate on-premises, cloud-based, and other databases.

Run the Replication Job

Once all the required configurations are made for the job, select the Google Cloud Storage table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.
