Azure Data Lake Storage Gen2 Using AAD WriteBack Connector

Intro

Azure Data Lake Storage Gen2 is a highly productive data lake solution. It extends Azure Storage to support enterprise‑grade data lake workloads on Azure. With this service, you can manage large volumes of data efficiently and accelerate your transition from proof of concept to production.

You connect to your Azure Data Lake Storage Gen2 Using AAD WriteBack account in the Data Center. This topic discusses the fields and menus that are specific to the Azure Data Lake Storage Gen2 Using AAD WriteBack connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in Adding a DataSet Using a Data Connector.

Prerequisites

To connect to your Azure Data Lake Storage Gen2 Using AAD WriteBack account and create a DataSet, you must have the following:

• Azure Application Client ID
• Azure Application Client Secret
• Tenant ID
• Account Name
• Container

Configuring Your Azure App

You must first create a Microsoft Azure Web App to obtain the necessary client ID and secret.

To configure an Azure App:

1. Login into Azure Portal.

2. Select Azure Active Directory > App Registrations > New Registration.

3. Fill out the registration form as follows:

• Name: Enter name for your application.
• Supported account types: Select an option to specify who can use this application or access this API.
• Redirect URI: Enter the redirect URI. The authentication response is sent to this URI after successfully authenticating the user. Providing the URI at this stage is optional and it can be changed later, but a value is required for most of the authentication scenarios.

4. Click Register. An overview of your registered App will appear.

5. The Application ID that appears here is the Client ID and the he Directory ID is the Tenant ID that you will enter in the Credentialspane in Domo.

6. Now, click on Certificates and secrets. Certificates can be used as secrets to prove the application’s identity when requesting a token. Also, can be referred to as public keys.

7. Click +New client secret.

8. Specify the client secret description and the expiry period for your client secret, and click Add.

9. Copy the value and paste it into the Client Secret field in the Connector credentials section in Domo.
