Integrate with Live AlloyDB Data in MuleSoft (via CData Connect Cloud)

The MuleSoft Anypoint Platform enables the building, deployment, and management of APIs and integrations, facilitating seamless connectivity across applications and systems. When combined with CData Connect Cloud, it provides access to AlloyDB data for visualizations, dashboards, and more. This article explains how to use CData Connect Cloud to create a live connection to AlloyDB and how to connect and access live AlloyDB data from the MuleSoft Anypoint Platform.

Prerequisites

Before configuring and using MuleSoft with CData Connect Cloud, you must first connect a data source to your CData Connect Cloud account. For more information, see the Connections section.

Additionally, you need to generate a Personal Access Token (PAT) on the Settings page. Be sure to copy it down, as it serves as your password during authentication.

Configure AlloyDB Connectivity for MuleSoft

Connectivity to AlloyDB from MuleSoft is made possible through CData Connect Cloud. To work with AlloyDB data from MuleSoft, we start by creating and configuring a AlloyDB connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "AlloyDB" from the Add Connection panel
3. Enter the necessary authentication properties to connect to AlloyDB.

   The following connection properties are usually required in order to connect to AlloyDB.

   • Server: The host name or IP of the server hosting the AlloyDB database.
   • User: The user which will be used to authenticate with the AlloyDB server.
   • Password: The password which will be used to authenticate with the AlloyDB server.

   You can also optionally set the following:

   • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
   • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

   Authenticating with Standard Authentication

   Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

   No further action is required to leverage Standard Authentication to connect.

   Authenticating with pg_hba.conf Auth Schemes

   There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

   Find instructions about authentication setup on the AlloyDB Server here.

   Authenticating with MD5 Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

   Authenticating with SASL Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

   Authenticating with Kerberos

   The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add AlloyDB Connection page and update the User-based permissions.

With the connection configured, you are ready to connect to AlloyDB data from MuleSoft.

Connecting to CData Connect Cloud

Follow these steps to establish a connection from Mulesoft to CData Connect Cloud through the JDBC driver:

1. Download and install the CData Connect Cloud JDBC driver.
   1. Open the Client Tools page of CData Connect Cloud.
   2. Locate MuleSoft and click on Download for Mac/Windows/Linux.
   3. Download and run the setup file.
   4. When the installation is complete, the JAR file can be found in the installation directory (inside the lib folder).
2. Log into Mulesoft Anypoint Studio or launch the desktop application.
3. Create a new Mulesoft project. The new project appears in a project folder.
4. In the Mule Palette located on the right, drag an HTTP Listener to the Message Flow area.
5. Click on the HTTP Listener to configure it.
6. Click the + sign on the right of Connector configuration. The HTTP Listener config dialog appears.
7. Configure the HTTP Listener, providing a Port on which to query your data, and click OK.
8. Provide a path on which to perform the actions. The HTTP Listener is now configured.
9. In the Mule Palette on the right, type database in the search bar.
10. Drag the database operation you want to perform to the Message Flow area. For this example, we choose Select.
11. Select Generic Connection from the Connection dropdown in the Database Config dialog.
12. Click the Configure button to configure the JDBC driver. Select Use local file from the drop-down list.
13. Locate the CData Connect Cloud JAR file from the JDBC driver installation and click OK.
14. Provide the following information:
    • URL: the URL for the connection, for example: jdbc:connect:Authscheme=Basic;user=username;password=password Note: the password is the PAT created in the Prerequisites section.
    • Driver class name: Enter the Driver class name as: cdata.jdbc.connect.ConnectDriver
15. Click Test Connection.
16. If the connection is successful, provide the SQL Query Text in the editor. You can see the table metadata on the right side in the Output tab.
17. In the Mule Palette, drag Transform Message to the Message Flow area.
18. Click Transform Message to configure it. Change the Output as follows:
19. Save your project and run it. In the console, Mulesoft starts initializing the dependencies.
20. Once you see the message, "Message source 'listener' on flow your_project_name successfully started", you can start querying your data at the endpoint you provided.
21. Query to check out the data using the Postman application (as shown below).

SQL Access to AlloyDB Data from Cloud Applications

Now you have a direct connection to live AlloyDB data from MuleSoft Anypoint Platform. You can create more connections to ensure seamless data flow, automate business processes, and manage APIs - all without replicating AlloyDB data.
