Access Live Cosmos DB Data in TIBCO Data Virtualization

TIBCO Data Virtualization (TDV) is an enterprise data virtualization solution that orchestrates access to multiple and varied data sources. When paired with the CData TIBCO DV Adapter for Cosmos DB, you get federated access to live Cosmos DB data directly within TIBCO Data Virtualization. This article walks through deploying an adapter and creating a new data source based on Cosmos DB.

With built-in optimized data processing, the CData TIBCO DV Adapter offers unmatched performance for interacting with live Cosmos DB data. When you issue complex SQL queries to Cosmos DB, the adapter pushes supported SQL operations, like filters and aggregations, directly to Cosmos DB. Its built-in dynamic metadata querying allows you to work with and analyze Cosmos DB data using native data types.

Deploy the Cosmos DB TIBCO DV Adapter

1. In a console, navigate to the bin folder in the TDV Server installation directory. If there is a current version of the adapter installed, you will need to undeploy it.

   .\server_util.bat -server localhost -user admin -password ******** -undeploy -version 1 -name CosmosDB
   

2. Extract the CData TIBCO DV Adapter to a local folder and deploy the JAR file (tdv.cosmosdb.jar) to the server from the extract location.

   .\server_util.bat -server localhost -user admin -password ******** -deploy -package /PATH/TO/tdv.cosmosdb.jar
   

You may need to restart the server to ensure the new JAR file is loaded properly, which can be accomplished by running the composite.bat script located at: C:\Program Files\TIBCO\TDV Server <version>\bin. Note that reauthenticating to the TDV Studio is required after restarting the server.

Sample Restart Call

.\composite.bat monitor restart

Create a Cosmos DB Data Source in TDV Studio

With the CData TIBCO DV Adapter for Cosmos DB, you can easily create a data source for Cosmos DB and introspect the data source to add resources to TDV.

Create the Data Source

1. Right-click on the folder you wish to add the data source to and select New -> New Data Source.
2. Scroll until you find the adapter (e.g. Cosmos DB) and click Next.
3. Name the data source (e.g. CData Cosmos DB Source).

4. Fill in the required 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.
5. Click Create & Close.

Introspect the Data Source

Once the data source is created, you can introspect the data source by right-clicking and selecting Open. In the dashboard, click Add/Remove Resources and select the Tables, Views, and Stored Procedures to include as part of the data source. Click Next and Finish to add the selected Cosmos DB tables, views, and stored procedures as resources.

After creating and introspecting the data source, you are ready to work with Cosmos DB data in TIBCO Data Virtualization just like you would any other relational data source. You can create views, query using SQL, publish the data source, and more.
