Validate Parallel Data with QuerySurge

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData API Driver for JDBC, QuerySurge can work with live Parallel data. This article explains how to connect to Parallel data from QuerySurge.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Parallel data. When you issue complex SQL queries to Parallel, the driver pushes supported SQL operations, like filters and aggregations, directly to Parallel 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 Parallel data using native data types.

Connecting to Parallel Data in QuerySurge

To connect to live Parallel 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

1. Download the CData API Driver for JDBC installer, unzip the package, and run the JAR file to install the driver.
2. Once the driver is installed, stop the Agent Service.
3. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData API Driver for JDBC\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
4. Restart the Agent Service.

For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.

Configure a New Connection to Parallel

1. Log into QuerySurge and navigate to the Admin view.
2. Click Configuration -> Connections in the Administration Tree.
3. Click Add to create a new connection.
4. In the QuerySurge Connection Wizard, click Next.
5. Name the connection (e.g. CData JDBC Connection to Parallel).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.api.APIDriver and click Next.

8. Set the Connection URL using the necessary connection properties to authenticate with Parallel. Your Connection URL will look something like the following:

   jdbc:api:Profile=C:\profiles\Parallel.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Parallel JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.api.jar
   	

   Fill in the connection properties and copy the connection string to the clipboard.

   The Parallel API uses API Key authentication via the x-api-key request header.

   Using API Key Authentication

   Your Parallel API key is required to create a connection. To obtain your API key:

   1. Log into your Parallel account at app.parallel.ai.
   2. Navigate to Settings or API Keys in your account dashboard.
   3. Generate or copy your API key.

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Parallel API key.

   Example connection string:

   Profile=C:\profiles\Parallel.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
   

   
9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM MonitorEvents LIMIT 1) and click Next.
10. 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 Parallel data in QuerySurge.

Compare Parallel Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying Parallel data with a QueryPair.

1. Select "Design Library" from the Design Menu
2. Click QueryPairs under QuerySurge Design
3. Click "Create New QueryPair"
4. Name the QueryPair and click Save
5. In either the Source or Target panes, select the connection created above (select the same connection to query Parallel twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM MonitorEvents
7. Click the "Design-Time Run" tab to execute the queries
8. When the query execution is finished, click "View Query Results" to see the Parallel data returned by the query
