Validate CockroachDB Data with QuerySurge

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for CockroachDB, QuerySurge can work with live CockroachDB data. This article walks through connecting to CockroachDB data from QuerySurge.

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

Connecting to CockroachDB Data in QuerySurge

To connect to live CockroachDB 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 JDBC Driver for CockroachDB 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 JDBC Driver for CockroachDB\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 CockroachDB

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 CockroachDB).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.cockroachdb.CockroachDBDriver and click Next.

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

   jdbc:cockroachdb:User=root;Password=root;Database=system;Server=localhost;Port=26257

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.cockroachdb.jar

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

   Set the following to connect to CockroachDB.

   • Server: The host name or IP address of the server.
   • Port: The port number of the CockroachDB server. If not specified, the default port is 26257.
   • Database: The name of the Cockroach database. If not specified, you connect to the user's default database.
   • User: The Cockroach DB user account used to authenticate.
   • Password: The password used to authenticate the user.
9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Orders 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 CockroachDB data in QuerySurge.

Compare CockroachDB Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying CockroachDB 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 CockroachDB twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM Orders
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 CockroachDB data returned by the query
