How do I use Snowflake External Tables with Wasabi?

Snowflake External Tables have been verified to use with Wasabi.

For further reference, please visit the Snowflake Documentation on configuring Wasabi storage.


  • Active Wasabi Storage account
  • A dataset supported by Snowflake uploaded to your Wasabi Bucket
  • Active Snowflake account
  • An understanding of Data Lake / Data Warehouse terminology and basic usage of Snowflake

NOTE: At this time, Snowflake must authorize using external s3 urls. You must open a support case with Snowflake ahead of time and ask that the s3 URL for the region your bucket lives can be authorized for your account. You can find the Wasabi S3 Urls here: Wasabi Service URLs article.


1. Upload Data to your Wasabi Bucket

To use Snowflake with Wasabi, you must have a dataset you wish to read from Wasabi. In this KB, we are using sample data generated with Faker. The sample data consists of 1000 files with 1000 rows of fake customer names, addresses, emails, phone numbers, companies, etc...

The data resides in the "snowflake-sample-test " bucket in the "us-east-2" region and a folder of "db1". The path to the data will be "//snowflake-sample-test/db1". You should adjust this accordingly when following along.


2. Create an SQL Worksheet

After logging into your Snowflake account, you want to create a new SQL Worksheet. This will be your scratchpad for working with the data living in Wasabi.




3. Create a Snowflake Database

After you have the Worksheet open, we need to make a Database to hold the information about the External Table and any related data.

We are going to run the two commands located below. In this KB, we use a database called "MY_TEST_WASABI_DATABASE". Be sure to adjust this accordingly for your use case.

The first command will create the database. The second will select it to be used for further queries in the Worksheet. After copying the commands in, select the first statement and hit the Run button in the top right hand corner(The blue button with an arrow on it).




4. Create a Snowflake Stage Object

A stage object must be created on Snowflake to tell where your data is being held or "staged". This is where we create the reference to a Wasabi Bucket, with the Region and Credentials.

Be sure to update the name of your stage, "wasabi_east2" in this example, the URL with your bucket name/path, region, and access keys.

Note: This configuration example discusses the use of Wasabi's us-east-2 storage region. To use other Wasabi storage regions, please use the appropriate Wasabi service URL as described in our Wasabi Service URLs article.

CREATE STAGE wasabi_east2
  URL = 's3compat://snowflake-sample-test/db1'
  REGION = 'us-east-2'


5. List the data in your Wasabi Account

After your stage has been created successfully, you should be able to list the contents of the files inside your Wasabi Bucket.

We will call the list query on the stage name.

LIST @wasabi_east2;

6. Create a Snowflake External Table

If you are successful at listing the contents of your Wasabi Bucket, we can then create the Snowflake External Table to be used to query your data. You will need to update the stage name, and the file format type based upon your dataset, and name chosen for the stage.


7. Run a Query on your data

After creating your table, you should be all set to run some queries against your data in order to validate it.



8. Success

You have now learned how to create a Snowflake External Table referencing data sitting on Wasabi.
