Automated Continuous Cosmos DB Replication to Vertica

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

Configure Vertica as a Replication Destination

Using CData Sync, you can replicate Cosmos DB data to Vertica. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection.
2. Select Vertica as a destination.
3. Enter the necessary connection properties:
   • Server: The host name or IP address of the Vertica database.
   • Database: The name of the database hosted on the Vertica Server.
   • User: The username of the authenticating Vertica database user.
   • Password: The password of the authenticating Vertica database user.
   • Port: The port for Vertica (5443 by default). This property is optional.
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

Configure the Cosmos DB Connection

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

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

   To obtain the connection string needed to connect to a Cosmos DB account using the SQL API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values:

   • AccountEndpoint: The Cosmos DB account URL from the Keys blade of the Cosmos DB account
   • AccountKey: In the Azure portal, navigate to the Cosmos DB service and select your Azure Cosmos DB account. From the resource menu, go to the Keys page. Find the PRIMARY KEY value and set AccountKey to this value.
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 Cosmos DB data to Vertica.
