Integrate Lakebase 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 JDBC Driver for Lakebase, you get live access to Lakebase data, directly within Informatica Cloud. In this article, we will walk through downloading and registering the Cloud Secure Agent, connecting to Lakebase 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 Lakebase 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 Lakebase JDBC Driver

With the Cloud Secure Agent installed and running, you are ready to connect to Lakebase 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.lakebase.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 Lakebase in Informatica Cloud

After installing the driver JAR file, you are ready to configure your connection to Lakebase 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 Lakebase 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.lakebase.LakebaseDriver
• JDBC Connection URL: Set this to the JDBC URL for Lakebase. Your URL will look similar to the following:
  
  

  jdbc:lakebase:DatabricksInstance=lakebase;Server=127.0.0.1;Port=5432;Database=my_database;InitiateOAuth=GETANDREFRESH;

  To connect to Databricks Lakebase, start by setting the following properties:
  • DatabricksInstance: The Databricks instance or server hostname, provided in the format instance-abcdef12-3456-7890-abcd-abcdef123456.database.cloud.databricks.com.
  • Server: The host name or IP address of the server hosting the Lakebase database.
  • Port (optional): The port of the server hosting the Lakebase database, set to 5432 by default.
  • Database (optional): The database to connect to after authenticating to the Lakebase Server, set to the authenticating user's default database by default.

  OAuth Client Authentication

  To authenicate using OAuth client credentials, you need to configure an OAuth client in your service principal. In short, you need to do the following:

  1. Create and configure a new service principal
  2. Assign permissions to the service principal
  3. Create an OAuth secret for the service principal

  For more information, refer to the Setting Up OAuthClient Authentication section in the Help documentation.

  OAuth PKCE Authentication

  To authenticate using the OAuth code type with PKCE (Proof Key for Code Exchange), set the following properties:

  • AuthScheme: OAuthPKCE.
  • User: The authenticating user's user ID.

  For more information, refer to the Help documentation.

  Built-In Connection String Designer

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

      java -jar cdata.jdbc.lakebase.jar
      

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

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

Create a Mapping for Lakebase Data

With the connection to Lakebase configured, we can now access Lakebase data in any Informatica process. The steps below walk through creating a mapping for Lakebase 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 Lakebase 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 Lakebase data with any of the supported connections in Informatica Cloud. Download a free, 30-day trial of the CData JDBC Driver for Lakebase and start working with your live Lakebase data in Informatica Cloud today.
