Connect to Hugging Face Data in DigitalSuite Studio through RunMyProcess DSEC

The CData JDBC Driver for Hugging Face implements JDBC Standards and enables a applications ranging from BI to IDE to connect with Hugging Face. In this article, we describe how to connect to Hugging Face data from Arkobi Digital RunMyProcess's DSEC and connect to Hugging Face in RunMyProcess.

Setting up EnterpriseConnect Agent

Configure the EnterpriseConnect Agent following the EnterpriseConnect page in the RunMyProcess documentation.

Setting up JDBC Adapter

The JDBC Adapter section describes the steps to connect to RDBMS through JDBC. Follow the steps and open the JDBC.config file.

1. Create a JSON entry for the CData JDBC Driver for Hugging Face, e.g.

   API = {
     "sqlDriver" : "...",
     "sqlSource" : "...",
     "sqlDriverPath" : "..."
   }
   

2. Set the "sqlDriver" field to the Class name for the CData JDBC Driver, e.g.
   cdata.jdbc.api.APIDriver
3. Set the "sqlSource" field to a JDBC URL for connecting to Hugging Face, e.g.
   jdbc:api: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.

   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';
   

   
4. Set the "sqlDriverPath" field to the name of the CData JDBC Driver JAR file, e.g.
   cdata.jdbc.api.jar

Sample JDBC.config File

#DBAgent Configuration
API = {"sqlDriver" : "cdata.jdbc.api.APIDriver", "sqlSource" = "jdbc:api:Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';","sqlDriverPath" = "cdata.jdbc.api.jar" }

Put the JDBC driver JAR file (cdata.jdbc.api.jar) into the same directory as unified-adapter-[version].jar.

Note: Make sure to put the CData license file (cdata.jdbc.api.lic) into the same directory. Since the license is generated based on the unique identifier of the machine where the product in installed, you will need an offline activation if you want to put the file on another machine.

Starting DigitalSuite EnterpriseConnect Agent

In Windows, start RunMyProcess DigitalSuite EnterpriseConnect Agent in Windows services. To start the application through command line, see Starting the EnterpriseConnect Agent in the RunMyProcess documents.

Starting the JDBC Adapter

Start the JDBC Adapter from runAdapter.bat. Once the Adapter is running, you can access the application through the agent address (e.g. 127.0.0.1:8080). Below is an example executing the command in Windows.

... > java -Djava.util.logging.config.file=./log.properties -cp lib/* org.runmyprocess.sec2.AdapterHandler :
2021-06-09 14:37:58|INFO|correlationId=|Searching for config file...
2021-06-09 14:37:58|INFO|correlationId=|Adapter Handler started with [JDBC] configuration
2021-06-09 14:37:59|INFO|correlationId=|agent address: 127.0.0.1:8080
2021-06-09 14:38:00.251:INFO::ConnectionThread: Logging initialized @1820ms to org.eclipse.jetty.util.log.StdErrLog
2021-06-09 14:38:00|INFO|correlationId=|onConnect() websocket connection between Agent and Adapter established

Once the DigitalSuite EnterpriseConnect Agent and JDBC Adapter are running, access http://localhost:(specified-port-number)/ through your browser to open the page shown below.

Check the availability of the JDBC Adapter using tools such as Postman or cURL. Here, we use Postman to send the HTTP POST request.

Configure the RequestHeader as follows:

Content-Type application/json

Configure the RequestBody as follows:

{
	"protocol":"JDBC",
	"data":{
		"DBType":"API",
		"sqlUsername":"",
		"sqlPassword":"",
		"sqlStatement":"SELECT * FROM Collections"
	}
}

If the JDBC.config file contains credential information, sqlUsername and sqlPassword can be left empty. If you are not sure of the table name, you can retrieve the list of tables using the request SELECT * FROM sys_tables

The request is successful if the Status is 200 and the Body contains Hugging Face data in JSON format.

Connect to Hugging Face through DSEC Agent in DigitalSuite Studio

Create a DigitalSuite Studio project and then create a Provider in the project.

• URL: The URL for accessing JDBC Agent (e.g. http:localhost:8080/)
• Authentication Scheme: Login/password
• Login: The value from agent.user in the application.properties file
• Password: agent.password in the application.properties file
• Secured: Checked
• Use DigitalSuite EnterpriseConnect: Checked
• With domain: The value from agent.domain in application.properties file

Next, create a Connector in the Provider.

• Connector URL: Leave this empty
• Architecture: REST/XML-RPC
• Method: POST
• Result format: JSON
• Accept media type: application/json
• Character set: Automatic
• Content: Same as the Request body used in the JDBC Adapter
• Content type: application/json

The JSON data we used as the Request body in JDBC Adapter:

{
	"protocol":"JDBC",
	"data":{
		"DBType":"API",
		"sqlUsername":"",
		"sqlPassword":"",
		"sqlStatement":"SELECT * FROM Collections"
	}
}

Open Launch Test to perform the test. The test is successful if Hugging Face data is shown in Result on the right pane.

Now you can use Hugging Face data in RunMyProcess DigitalSuite Studio through DSEC.
