How to connect to Nuclia Data from IntelliJ

The CData JDBC Driver for Nuclia enables you to access Nuclia as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to Nuclia data in IntelliJ.

Create a JBDC Data Source for Nuclia

Follow the steps below to add the driver JAR and define connection properties required to connect to Nuclia data.

1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.

2. In the Data Source Properties dialog that appears, the following properties are required:

   • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.api.jar, located in the installation directory.
   • JDBC Driver Class: In this menu, select cdata.jdbc.api.APIDriver from the list.

   • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:api: and includes connection properties separated with semicolons.

     Using API Key Authentication

     Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:

     1. Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
     2. Navigate to your Knowledge Box settings
     3. Go to the Service Accounts section
     4. Create a new service account or copy an existing API key

     After obtaining your API key, set the following connection properties:

     • AuthScheme: Set this to APIKey.
     • APIKey: Set this to your Nuclia service account API key.
     • KbId: Set this to your Knowledge Box UUID.
     • Zone: Set this to your Nuclia deployment zone (e.g., aws-us-east-2-1).

     Example Connection String

     Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;
     

     Connecting to Nuclia

     Once the authentication is configured, you can connect to Nuclia and query data from any of the available tables such as Resources, KnowledgeBox, LabelSets, and ProcessingStatus.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.api.jar
     

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

     

     A typical JDBC URL is the following:

     jdbc:api:Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;

Edit and Save Nuclia Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor.
