Connect to Certinia Data in as an External Source in Dremio

The CData JDBC Driver for Certinia implements JDBC Standards and allows various applications, including Dremio, to work with live Certinia data. Dremio is a data lakehouse platform designed to empower self-service, interactive analytics on the data lake. With the CData JDBC Driver, you can include live Certinia data as a part of your enterprise data lake. This article describes how to connect to Certinia data from Dremio as an External Source.

The CData JDBC Driver enables high-speed access to live Certinia data in Dremio. Once you install the driver, authenticate with Certinia and gain immediate access to Certinia data within your data lake. By surfacing Certinia data using native data types and handling complex filters, aggregations, & other operations automatically, the CData JDBC Driver grants seamless access to Certinia data.

Build the ARP Connector

To use the CData JDBC Driver in Dremio, you need to build an Advanced Relation Pushdown (ARP) Connector. You can view the source code for the Connector on GitHub or download the ZIP file (GitHub.com) directly. Once you copy or extract the files, run the following command from the root directory of the connector (the directory containing the pom.xml file) to build the connector.

mvn clean install

Once the JAR file for the connector is built (in the target directory), you are ready to copy the ARP connector and JDBC Driver to your Dremio instance.

Installing the Connector and JDBC Driver

Install the ARP Connector to %DREMIO_HOME%/jars/ and the JDBC Driver for Certinia to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

docker cp PATH\TO\dremio-certinia-plugin-20.0.0.jar dremio_image_name:/opt/dremio/jars/

JDBC Driver for Certinia

docker cp PATH\TO\cdata.jdbc.certinia.jar dremio_image_name:/opt/dremio/jars/3rdparty/

Connecting to Certinia

Certinia will now appear as an External Source option in Dremio. The ARP Connector built uses a JDBC URL to connect to Certinia data. The JDBC Driver has a built-in connection string designer that you can use (see below).

Built-in Connection String Designer

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

java -jar cdata.jdbc.certinia.jar

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

There are several authentication methods available for connecting to Certinia: login credentials, SSO, and OAuth.

Authenticating with a Login and Token

Set the User and Password to your login credentials. Additionally, set the SecurityToken. By default, the SecurityToken is required, but you can make it optional by allowing a range of trusted IP addresses.

To disable the security token:

1. Log in to Certinia and enter "Network Access" in the Quick Find box in the setup section.
2. Add your IP address to the list of trusted IP addresses.

To obtain the security token:

1. Open the personal information page on certinia.com.
2. Click the link to reset your security token. The token will be emailed to you.
3. Specify the security token in the SecurityToken connection property or append it to the Password.

Authenticating with OAuth

If you do not have access to the user name and password or do not want to require them, use the OAuth user consent flow. See the OAuth section in the Help for an authentication guide.

Connecting to Certinia Sandbox Accounts

Set UseSandbox to true (false by default) to use a Certinia sandbox account. Ensure that you specify a sandbox user name in User.

NOTE: To use the JDBC Driver in Dremio, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

Add the Runtime Key (RTK) to the JDBC URL. You will end up with a JDBC URL similar to the following:

jdbc:certinia:RTK=5246...;User=myUser;Password=myPassword;Security Token=myToken;InitiateOAuth=GETANDREFRESH

Access Certinia as an External Source

To add Certinia as an External Source, click to add a new source and select Certinia. Copy the JDBC URL and paste it into the New Certinia Source wizard.

Save the connection and you are ready to query live Certinia data in Dremio, easily incorporating Certinia data into your data lake.
