Automated Continuous Google Cloud Storage Replication to Local Delimited Files

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Google Cloud Storage data into local delimited files (CSV/TSV), allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

Configure CSV/TSV as a Replication Destination

Using CData Sync, you can replicate Google Cloud Storage data to delimited files, like CSV or TSV. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection.
2. Select CSV as a destination.
3. Enter the necessary connection properties. To connect to a directory for storing delimited files, set the following:
   • Destination Folder: Set this location on the disk for the delimited files.
   • Include Column Headers: Set this to True for the first row in each file to represent the column names.
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

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 ensure that the connection is configured properly.
5. Click Save 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, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

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.

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after 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 delimited files.
