Managing data ingestion from Azure Blob Storage to Snowflake can be cumbersome. Manual processes lead to inefficiencies and potential errors while also increasing operational overhead. 

But what if you could automate the process, ensure data integrity, and leverage real-time analytics?

In this guide, I’ll walk you through the automated process of Snowflake Snowpipe Azure Integration. We’ll cover everything from configuring your Azure Blob Storage environment to creating the necessary Snowflake Snowpipe components and monitoring the data loading process. Let’s get started!

What is Azure?

Microsoft Azure Logo
  • Microsoft Azure is a cloud computing platform and a set of services provided by Microsoft. 
  • It offers a wide range of services, such as:
    • computing services in the form of virtual machines
    • storage services such as blob and file storage, 
    • networking services such as load balancers, 
    • databases such as Cosmos DB and SQL 
    • analytics such as Azure Synapse Analytics, 
    • machine learning, such as Azure Machine Learning, etc.

What is Snowpipe?

Snowpipe Logo.
  • Snowflake Snowpipe is a real-time data ingestion service provided by Snowflake.
  • It automatically ingests data from cloud platforms like Azure and Google Cloud and loads it into the Snowflake database, reducing data availability latency.

Why Integrate Snowpipe with Azure?

Traditional data loading processes face several challenges that can hinder your efficiency and reliability, some of which are listed below. With the integration, you can overcome these challenges. 

  • Data Latency: Although Azure Blob Storage is efficient for storing large volumes of data, it typically requires batch processes to load the data into the analytics platform. Snowflake Snowpipe Azure automates this entire process, reducing data availability latency.
  • Scalability: Handling fluctuating volumes of data can overload the resources, leading to performance issues. Snowpipe Azure integration enables streamless data loading without affecting the performance.
  • Cost Management: It follows the pay-as-you-go model, which minimizes resource usage only when data is loaded into the Snowpipe.

Loading data from Azure Blob Storage to Snowflake using Snowpipe

In this section, you will see how you can integrate your Azure Blob storage account with Snowpipe and ultimately load the data directly from Blob Storage to the table where you want to store it in Snowflake, therefore forming your Snowflake Snowpipe Azure pipeline.

Step 1: Create a table in Snowflake

We need to create a table with the required schema and compatible file columns, so that we can load our data in that table.

You can create a table using the command:

CREATE TABLE bank_transactions
TransactionNo INT,
FromAccount INT,
ToAccount INT,
Amount Number,
TypeOfTransaction VARCHAR(20),
TranDescription VARCHAR(200),
Source VARCHAR(100)

Note: <bank_transactions> is the table’s name, which you can give as your choice.

Creation of Table BANK_TRANSACTIONS.

Step 2: Configuring the Azure Storage Account

2. a) We need to create a Storage Account on Azure using the user interface and name it accordingly.

For this tutorial, I have named it ‘snowflakesnowpipe1234’.

Note: While configuring your storage account, you need to select StorageV2 or higher.

Deployment Configuration in Azure Blob Storage.

2. b) After the successful creation of the Storage Account, we need to create a Container so that we can stage our files that will be loaded in Snowflake.

Creation of Containers.

2. c) After creating a container, we need to create a storage queue as an endpoint of the event subscription.

Storage Queue Creation in Azure.

2.d) We need to create the Event Grid Subscription for the blob container and set the endpoint for the storage queue.

Creation of Event Grid Subscription.

2. e) To create an Integration in Snowflake, you must have the Storage Queue URL and the Azure Acting Directory ID.

If we go to Queues, we will get the URL.

2. f) For Azure Active Directory ID, Go to Home >> Active Directory.Note: The Tenant ID is your Azure Active Directory ID

Get the Tenant ID.

Step 3: Create a Notification Integration in Snowflake

We need to create an integration in Snowflake that would allow Snowflake access to our Azure Blob Storage Account.

You can create an integration using the following command:


Note: Use the Queue URL and the Azure Active Directory ID in place of primary_uri and azure_tenant_id.

Creation of BANKING_SNOWPIPE_EVENT Integration.

To verify the integration that you just created, use the following command:


Step 4: Authenticate the Azure Account and Grant Access

We need to perform this step so that Azure authenticates our Snowflake account.

4. a) You can execute the DESC integration command to display the integration description and use the AZURE_CONSENT_URL to establish a protocol between your Azure Account and  Snowflake Account.

AZURE_CONSENT_URL Authentication.

4. b) Copy the URL, open it in a new window, and accept the permissions requested.

Granting necessary permissions to Snowflake.

4. c) Grant Snowflake access to the Storage Queue.

4. d) Go to the Enterprise Applications for the Application Details.

Your Snowflake Application Name and ID will be displayed. Keep those in mind; we will need them later.

Properties of Enterprise Applications.

Step 5: Grant Access to the Storage Queue through IAM

We need to give the enterprise application access to our storage queue to load data into Snowflake automatically. Perform the given steps to grant access to your storage queue.

What we are essentially doing is adding a new custom role and assigning a few permissions to that role. In members, we will add our new enterprise application to that role.

5. a) Go to Storage Account >> IAM.

5.b) To add a new role assignment, Go to Role Assignment >> Add >> Add Role  Assignment.

5. c) Assign the Role to the Snowflake Application Name.

Adding Role Assignment through IAM.

Step 6: Blob Service Endpoint and SAS

To create a snowflake stage, we will need a blob service endpoint and shared access signature.

6. a) To get the Blob Service Endpoint, go to Storage Account >> Settings >> Endpoints.

Blob Service Endpoint and SAS.

6. b) To get the Shared Access Signature, go to Security + networking.

Shared Access Signature.

6. c) To create a shared access signature string, check the Allowed Services, Resources Types, Start and End Expiry Date, and Time. After configuring everything, click on the Generate SAS connection string.

Generate SAS and Connection String.

6.d)Scroll down and keep the Blob Service SAS URL.

Step 7: Create a stage and pipe in Snowflake

7. a) You must create a stage in Snowflake where the data would be kept using the following command:

url = ''
credentials = (azure_sas_token='');

Note: The URL will not have the HTTP part; it will be Azure, and the Sas Token will remove the HTTP part. It should start with ‘?’.

Example for the above command:

url = 'azure://'
credentials = (azure_sas_token='?sv=2022-11-02&ss=bfqt&srt=co&sp=rwdlaciytfx&se=2024-08-01T18:47:43Z&st=2024-07-02T10:47:43Z&spr=https&sig=3MeWvsw4MW%2BtpaD7iU6XhD1gijsuTe327YP0sbX2Aqs%3D');

After you have created the stage, you will receive a status saying stage created.

Creation of Stage Area.

7. b) Next, we need to create a pipe to ingest our data from Azure to Snowflake

We can use the following query to create the snowpipe:

file_format = (type='CSV');

Note: Here, auto_ingest = true signifies that the files will be automatically ingested into Snowflake once they are in the staging area.


7. c) Next, we need to upload our files to Azure. You can do so by navigating to the blob container you just created and dragging and dropping your file into the container.

Loading Data into Azure Blob Storage.

7.d) In the worksheet, use the command to look at the files present in the stage:


Here, you can see that the data you uploaded to Azure is already in the stage. 

7. e) Refresh the pipe using the command given below:

Csv file successfully loaded into the pipe.

7. f) Now, run the SELECT command to view the data that has been loaded.

The data which is loaded.
