Integrate Hugging Face Data in Your Informatica Cloud Instance

Informatica Cloud allows you to perform extract, transform, and load (ETL) tasks in the cloud. With the Cloud Secure Agent and the CData API Driver for JDBC, you get live access to Hugging Face data, directly within Informatica Cloud. In this article, we will walk through downloading and registering the Cloud Secure Agent, connecting to Hugging Face through the JDBC Driver and generating a mapping that can be used in any Informatica Cloud process.

Informatica Cloud Secure Agent

To work with the Hugging Face data through the JDBC Driver, install the Cloud Secure Agent.

1. Navigate to the Administrator page in Informatica Cloud
2. Select the Runtime Environments tab
3. Click "Download Secure Agent"
4. Make note of the Install Token
5. Run the installer on the client machine and register the Cloud Secure Agent with your username and install token

NOTE: It may take some time for all of the Cloud Secure Agent services to get up and running.

Connecting to the Hugging Face JDBC Driver

With the Cloud Secure Agent installed and running, you are ready to connect to Hugging Face through the JDBC Driver.

Adding the JDBC Driver to the Secure Agent Machine

1. Navigate to the following directory on the Secure Agent machine:

   %Secure Agent installation directory%/ext/connectors/thirdparty/

2. Create a folder and add the driver JAR file (cdata.jdbc.api.jar) based on the type of mapping that you want to configure.

   For mappings, create the following folder and add the driver JAR file:

   informatica.jdbc_v2/common

   For mappings in advanced mode, also create the following folder and add the driver JAR file:

   informatica.jdbc_v2/spark

3. Restart the Secure Agent.

Connecting to Hugging Face in Informatica Cloud

After installing the driver JAR file, you are ready to configure your connection to Hugging Face in Informatica Cloud. Start by clicking the Connections tab and clicking New Connection. Fill in the following properties for the connection:

• Connection Name: Name your connection (i.e.: CData Hugging Face Connection)
• Type: Select "JDBC_V2"
• Runtime Environment: Select the runtime environment where you installed the Secure Agent
• JDBC Driver Class Name: The name of the JDBC driver class: cdata.jdbc.api.APIDriver
• JDBC Connection URL: Set this to the JDBC URL for Hugging Face. Your URL will look similar to the following:
  
  

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

  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.

  
• Username: Set this to a placeholder value (since Hugging Face does not require a username)
• Password: Set this to a placeholder value (since Hugging Face does not require a password)

Create a Mapping for Hugging Face Data

With the connection to Hugging Face configured, we can now access Hugging Face data in any Informatica process. The steps below walk through creating a mapping for Hugging Face to another data target.

1. Navigate to the Data Integration page
2. Click New.. and select Mapping from the Mappings tab
3. Click the Source Object and in the Source tab, select the Connection and set the Source Type
4. Click "Select" to choose the table to map
5. In the Fields tab, select the fields from the Hugging Face table to map
6. Click the Target object and configure the Target source, table and fields. In the Field Mapping tab, map the source fields to the target fields.

With the mapping configured, you are ready to start integrating live Hugging Face data with any of the supported connections in Informatica Cloud. Download a free, 30-day trial of the CData API Driver for JDBC and start working with your live Hugging Face data in Informatica Cloud today.
