Access and validate Cosmos DB data in QuerySurge using the CData JDBC Driver.
QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for Cosmos DB, QuerySurge can work with live Cosmos DB data. This article walks through connecting to Cosmos DB data from QuerySurge.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Cosmos DB data. When you issue complex SQL queries to Cosmos DB, the driver pushes supported SQL operations, like filters and aggregations, directly to Cosmos DB and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Cosmos DB data using native data types.
Connecting to Cosmos DB Data in QuerySurge
To connect to live Cosmos DB data from QuerySurge, you need to deploy the JDBC Driver JAR file to your QuerySurge Agent(s) and add a new connection from the QuerySurge Admin view.
Deploy the JDBC Driver
- Download the CData JDBC Driver for Cosmos DB installer, unzip the package, and run the JAR file to install the driver.
- Once the driver is installed, stop the Agent Service.
- Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Cosmos DB\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
- Restart the Agent Service.
For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.
Configure a New Connection to Cosmos DB
- Log into QuerySurge and navigate to the Admin view.
- Click Configuration -> Connections in the Administration Tree.
- Click Add to create a new connection.
- In the QuerySurge Connection Wizard, click Next.
- Name the connection (e.g. CData JDBC Connection to Cosmos DB).
- Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
- Set the Driver Class to cdata.jdbc.cosmosdb.CosmosDBDriver and click Next.
Set the Connection URL using the necessary connection properties to authenticate with Cosmos DB. Your Connection URL will look something like the following:
jdbc:cosmosdb:AccountEndpoint=myAccountEndpoint;AccountKey=myAccountKey;
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Cosmos DB JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.cosmosdb.jar
Fill in the connection properties and copy the connection string to the clipboard.
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.
- Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Customers LIMIT 1) and click Next.
- Click Test Connection to ensure the connection is configured properly and click Save to add the connection.
Once the connection is added, you can write SQL queries against your Cosmos DB data in QuerySurge.
Compare Cosmos DB Data Queries with a QueryPair
With the connection configured, you can follow the steps below to compare querying Cosmos DB data with a QueryPair.
- Select "Design Library" from the Design Menu
- Click QueryPairs under QuerySurge Design
- Click "Create New QueryPair"
- Name the QueryPair and click Save
- In either the Source or Target panes, select the connection created above (select the same connection to query Cosmos DB twice or another connection to perform a comparison)
- Write queries in the Editor for each pane, e.g. SELECT * FROM Customers
- Click the "Design-Time Run" tab to execute the queries
- When the query execution is finished, click "View Query Results" to see the Cosmos DB data returned by the query
