Access and validate Azure Data Catalog 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 Azure Data Catalog, QuerySurge can work with live Azure Data Catalog data. This article walks through connecting to Azure Data Catalog data from QuerySurge.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Azure Data Catalog data. When you issue complex SQL queries to Azure Data Catalog, the driver pushes supported SQL operations, like filters and aggregations, directly to Azure Data Catalog 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 Azure Data Catalog data using native data types.
Connecting to Azure Data Catalog Data in QuerySurge
To connect to live Azure Data Catalog 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 Azure Data Catalog 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 Azure Data Catalog\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 Azure Data Catalog
- 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 Azure Data Catalog).
- Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
- Set the Driver Class to cdata.jdbc.azuredatacatalog.AzureDataCatalogDriver and click Next.
Set the Connection URL using the necessary connection properties to authenticate with Azure Data Catalog. Your Connection URL will look something like the following:
jdbc:azuredatacatalog:InitiateOAuth=GETANDREFRESH
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Azure Data Catalog JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.azuredatacatalog.jar
Fill in the connection properties and copy the connection string to the clipboard.
You can optionally set the following to read the different catalog data returned from Azure Data Catalog.
- CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name
Connect Using OAuth Authentication
You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.
- Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Tables 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 Azure Data Catalog data in QuerySurge.
Compare Azure Data Catalog Data Queries with a QueryPair
With the connection configured, you can follow the steps below to compare querying Azure Data Catalog 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 Azure Data Catalog twice or another connection to perform a comparison)
- Write queries in the Editor for each pane, e.g. SELECT * FROM Tables
- Click the "Design-Time Run" tab to execute the queries
- When the query execution is finished, click "View Query Results" to see the Azure Data Catalog data returned by the query
