If you’re using ZappySys SSIS Power Pack to manage files in Azure Data Lake Storage Gen2 (ADLS v2)—including hierarchical folders required by many modern data lake workloads (for example, Parquet-based pipelines)—this guide walks you through the complete setup process step by step.

Steps

Validating your Azure Storage Account Is Gen2 (ADLS v2)

Before connecting from SSIS, confirm that your Azure Storage Account is ADLS Gen2–enabled, which means it supports a hierarchical namespace.

1. Check the Storage Account Type. Go to Azure Portal → Storage Accounts and verify that your account is ADLS v2 (Gen2).
   

   Validate Your Account Type

2. Open the storage account
3. Locate Hierarchical namespace
4. Ensure it is set to Enabled
5. If hierarchical namespace is not enabled, click Enable
6. During the wizard, Azure may require Soft Delete to be turned off
7. Disable both soft delete options if prompted

Important
Enabling hierarchical namespace is a one-way operation. Once enabled, the storage account cannot be reverted to a flat namespace.

Connect Azure ADLS Gen2 in SSIS

ZappySys supports multiple authentication methods. The two most common options are Access Key and SAS Token.

Option A: Connect Using Storage Account Access Key. This is the simplest method and works well for internal or controlled environments.

1. Obtain the Access Key.
2. Go to your Storage Account.
3. Navigate to Access keys.
4. Copy Key1 or Key2.

5. Create or open an SSIS project in Visual Studio and add the ZappySys Azure Storage Task.
6. Create a new connection and choose Access Key authentication.
7. Enter the Storage Account Name and Access Key and test the connection.
   

   Connect Azure Storage Account in SSIS – Using Access Key Method

Option B: Connect Using SAS Token (Recommended for Least-Privilege Access). SAS tokens are ideal when you want restricted, time-bound, or container-level access.

1. Navigate to the Target Container
2. Open Storage Account → Containers.
3. Select the container you want to grant access to.
   

   Containers in Azure Portal

4. Click Generate SAS to generate a Container-Level SAS Token.
5. Select required permissions (Read / Write / List / Delete).
6. Set expiration date.
7. Generate and copy the SAS URL.
   

   Azure Storage Account – Generate SAS Token (Container Level)

Recommended: Use SAS URL for quicker and more reliable configuration. While SAS Token authentication is still supported, Copy SAS URL is easier and more user-friendly because it already includes the container path. When you paste the SAS URL into the Connection UI, the container name is automatically detected, eliminating the need to enter it as a separate step manually.

8. Go to our Microsoft Azure Blob connection and use the SAS Token in SSIS
9. Choose SAS Token authentication in the Azure Storage Task and provide the SAS Token or URL.
10. Test the connection and click OK to save the configuration.

Download Files from Azure ADLS Gen2 in SSIS

1. Inside the ZappySys Azure Storage Task, select the connection created in the previous step.
2. Use the option DownloadAzure File(s) to local directory.
3. Select the Parquet or CSV files you want to download. You can pull files from date-partitioned folders and use dynamically built paths with SSIS variables.
   

   Download Azure Storage Files in SSIS (ADSL v2 or Legacy Blob Storage)

Upload Files to Azure ADLS Gen2 in SSIS

1. Change the Storage Action to Upload local file(s) to Azure.
2. Upload single files or entire folders.
3. Choose between Overwrite or skip existing files.
4. Use the ZappySys placeholder engine to dynamically build source and destination paths.

Other Azure Storage File Operations

The Azure Storage Task supports many additional operations:

• Sync folders
• Create containers or directories
• Delete files or folders
• List files recursively

What is Azure Table Storage?

Azure Table storage stores large amounts of structured data. The service is a NoSQL datastore which accepts authenticated calls from inside and outside the Azure cloud. Azure tables are ideal for storing structured, non-relational data. Common uses of Table storage include:

Microsoft Azure Table Storage Introduction

• Storing TBs of structured data capable of serving web-scale applications
• Storing datasets that don’t require complex joins, foreign keys, or stored procedures and can be denormalized for fast access
• Quickly querying data using a clustered index
• Accessing data using the OData protocol and LINQ queries with WCF Data Service .NET Libraries

You can use Table storage to store and query huge sets of structured, non-relational data, and your tables will scale as demand increases.

Getting Started

In order to start, we will show several examples. Zappysys includes an SSIS Azure Table Storage Source. Here we are showing you is, how to Read/Write Azure Table Storage data in SSIS.

You can connect to your Azure Storage Account by entering your storage account credentials. Here I am showing an example of the use of the local Azure Storage Emulator.

Setup Azure Storage client tools and Create Table

1. Once you have downloaded and installed a storage emulator You can launch Microsoft Azure Storage Emulator from its Physical location or from the desktop or start menu shortcut.
   

   Azure Storage Emulator Physical Location

2. If you can see the below-attached Command Prompt screen after Emulator started. Then you can proceed to start Microsoft Azure Storage Explorer as the Azure Storage Emulator is started successfully.

4. If you don’t have Azure Storage account then it’s easy to get FREE Trial Azure Storage account or use your MSDN to get credit each month which will be more than enough for real testing. If you prefer to avoid all this hassle then Microsoft provides another great way to test Azure Storage functionality is totally offline mode on your local machine. You can just download Azure Storage Emulator and start testing.
5.  Click here to learn more about how to configure Azure Storage Emulator for Testing and Development purposes. In order to connect to Azure Storage Service from SSIS, you will need Storage AccountName and an AccessKey. Ask your SysAdmin or responsible person to provide that information to you. Here are sample Account Name and Access Key(this is just example key which may differ in your case)
   

   Account Name: mystorageaccount 
   Access Key: Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==

6. For Creating a Tables, First of all, you need to go to Microsoft Storage Explorer Window. Then you can go through like this way (Storage Accounts –> Emulator – Default Ports(Key) –> Tables. Right-click on Tables and Select Create Table and put your table name you want.
