Trello JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Trello data including List, Cards, Boards, and more!



Use the CData JDBC Driver to connect to Trello as an External Source in Dremio.

The CData JDBC Driver for Trello implements JDBC Standards and allows various applications, including Dremio, to work with live Trello 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 Trello data as a part of your enterprise data lake. This article describes how to connect to Trello data from Dremio as an External Source.

The CData JDBC Driver enables high-speed access to live Trello data in Dremio. Once you install the driver, authenticate with Trello and gain immediate access to Trello data within your data lake. By surfacing Trello data using native data types and handling complex filters, aggregations, & other operations automatically, the CData JDBC Driver grants seamless access to Trello 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 Trello to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

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

JDBC Driver for Trello

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

Connecting to Trello

Trello will now appear as an External Source option in Dremio. The ARP Connector built uses a JDBC URL to connect to Trello 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 Trello JDBC Driver. Double-click the JAR file or execute the jar file from the command line.

java -jar cdata.jdbc.trello.jar

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

Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

  • Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
  • OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.

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:trello:RTK=5246...;APIKey=myApiKey;Token=myGeneratedToken;InitiateOAuth=GETANDREFRESH

Access Trello as an External Source

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

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