Connect to Hugging Face Data in Aqua Data Studio

The CData JDBC Driver for Hugging Face integrates Hugging Face data with wizards and analytics in IDEs like Aqua Data Studio. This article shows how to connect to Hugging Face data through the connection manager and execute queries.

Create a JDBC Data Source

You can use the connection manager to define connection properties and save them in a new JDBC data source. The Hugging Face data source can then be accessed from Aqua Data Studio tools.

1. In Aqua Data Studio, select Register Server from the Servers menu.
2. In the Register Server form, select the 'Generic - JDBC' connection.
3. Enter the following JDBC connection properties:
   • Name: Enter a name for the data source; for example, Hugging Face.
   • Driver Location: Click the Browse button and select the cdata.jdbc.api.jar file, located in the lib subfolder of the installation directory.
   • Driver: Enter the Driver's class name, cdata.jdbc.api.APIDriver.

   • URL: Enter the JDBC URL, which starts with jdbc:api: and is followed by a semicolon-separated list of connection properties.

     HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

     Using API Key Authentication

     To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

     1. Log in to your HuggingFace account at https://huggingface.co
     2. Navigate to Settings > Access Tokens
     3. Click "New token" to create a new access token
     4. Select the appropriate permissions (read or write)
     5. Copy the token value

     After obtaining your access token, set the following connection properties:

     • AuthScheme: Set this to APIKey.
     • APIKey: Set this to your HuggingFace access token.

     Example connection string

     Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';
     

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Hugging Face 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 below:

     jdbc:api:Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';

   

Query Hugging Face Data

You can now query the tables exposed.
