How to Connect DBeaver to Kafka via a JDBC Driver



Manage Kafka data with visual tools in DBeaver like the query browser.

The CData JDBC Driver for Apache Kafka implements JDBC standards that enable third-party tools to interoperate, from wizards in IDEs to business intelligence tools. This article shows how to connect to Kafka data with wizards in DBeaver and browse data in the DBeaver GUI.

Create a JDBC Data Source for Kafka Data

Follow the steps below to load the driver JAR in DBeaver.

  1. Open the DBeaver application and, in the "Database" menu, select the "Driver Manager" option. Click "New" to open the "Create new driver" form.
  2. In the Settings tab:
    • Set Driver Name to a user-friendly name for the driver (e.g. CData JDBC Driver for Apache Kafka).
    • Set Class Name to the class name for the JDBC driver: cdata.jdbc.apachekafka.ApacheKafkaDriver.
    • Set URL Template to jdbc:apachekafka:.
  3. In the Libraries tab, click "Add File," navigate to the "lib" folder in the installation directory (C:\Program Files\CData[product_name] XXXX\) and select the JAR file (cdata.jdbc.ApacheKafka.jar).

Create a Connection to Kafka Data

Follow the steps below to add credentials and other required connection properties.

  1. In the "Database" menu, click "New Database Connection."
  2. In the "Connect to a database" wizard that results, select the driver you just created (e.g. CData JDBC Driver for Apache Kafka) and click "Next >."
  3. On the Main tab of the configuration wizard, set the JDBC URL, using the required connection properties:

    Set BootstrapServers and the Topic properties to specify the address of your Apache Kafka server, as well as the topic you would like to interact with.

    Authorization Mechanisms

    • SASL Plain: The User and Password properties should be specified. AuthScheme should be set to 'Plain'.
    • SASL SSL: The User and Password properties should be specified. AuthScheme should be set to 'Scram'. UseSSL should be set to true.
    • SSL: The SSLCert and SSLCertPassword properties should be specified. UseSSL should be set to true.
    • Kerberos: The User and Password properties should be specified. AuthScheme should be set to 'Kerberos'.

    You may be required to trust the server certificate. In such cases, specify the TrustStorePath and the TrustStorePassword if necessary.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.apachekafka.jar

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

    Below is a typical connection string:

    jdbc:apachekafka:User=admin;Password=pass;BootStrapServers=https://localhost:9091;Topic=MyTopic;
  4. Click "Test Connection ..." to ensure you have configured the connection properly.
  5. Click "Finish."

Query Kafka Data

You can now query information from the tables exposed by the connection: Right-click a Table and then click View Table. The data is available on the Data tab.
