Automated Continuous Teradata Replication to Snowflake

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Teradata data into your Snowflake instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

Configure Snowflake as a Replication Destination

Using CData Sync, you can replicate Teradata data to Snowflake. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection.
2. Select Snowflake as a destination.
3. Enter the necessary connection properties. To connect to Snowflake, set the following:
   • User: The username provided for authentication with the Snowflake database
   • Password: The Snowflake user's password
   • AuthScheme: The authentication scheme used. Accepted entries are PASSWORD, OKTA
   • Account: The Account provided for authentication with Snowflake
   • URL: the URL of the Snowflake database instance, for example: https://myaccount.snowflakecomputing.com
   • Warehouse: The name of the Snowflake warehouse
   • Database: The name of the Snowflake database
   • Schema: The schema of the Snowflake database
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

Configure the Teradata Connection

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

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

   To connect to Teradata, provide authentication information and specify the database server name.

   • User: Set this to the username of a Teradata user.
   • Password: Set this to the password of the Teradata user.
   • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
   • Port: Specify the port the server is running on.
   • Database: Specify the database name. If not specified, the default database is used.
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 Teradata data to Snowflake.
