Integrate CockroachDB Data in Pentaho Data Integration

The CData JDBC Driver for CockroachDB enables access to live data from data pipelines. Pentaho Data Integration is an Extraction, Transformation, and Loading (ETL) engine that data, cleanses the data, and stores data using a uniform format that is accessible.This article shows how to connect to CockroachDB data as a JDBC data source and build jobs and transformations based on CockroachDB data in Pentaho Data Integration.

Configure to CockroachDB Connectivity

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.

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.

When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Below is a typical JDBC URL:

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

Save your connection string for use in Pentaho Data Integration.

Connect to CockroachDB from Pentaho DI

Open Pentaho Data Integration and select "Database Connection" to configure a connection to the CData JDBC Driver for CockroachDB

1. Click "General"
2. Set Connection name (e.g. CockroachDB Connection)
3. Set Connection type to "Generic database"
4. Set Access to "Native (JDBC)"
5. Set Custom connection URL to your CockroachDB connection string (e.g.
   

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

6. Set Custom driver class name to "cdata.jdbc.cockroachdb.CockroachDBDriver" 👁 Configuring the JDBC Driver connection.
   
7. Test the connection and click "OK" to save. 👁 Saving the connection.
   

Create a Data Pipeline for CockroachDB

Once the connection to CockroachDB is configured using the CData JDBC Driver, you are ready to create a new transformation or job.

1. Click "File" >> "New" >> "Transformation/job"
2. Drag a "Table input" object into the workflow panel and select your CockroachDB connection. 👁 Configuring the Table input object
   
3. Click "Get SQL select statement" and use the Database Explorer to view the available tables and views. 👁 Selecting data (QuickBooks Online is shown).
   
4. Select a table and optionally preview the data for verification. 👁 Previewing the data (QuickBooks Online is shown).
   

At this point, you can continue your transformation or jb by selecting a suitable destination and adding any transformations to modify, filter, or otherwise alter the data during replication.
