Amazon S3 for Snowflake

As discussed in cloud bucket storage setup, Amazon S3 is required for several data-related use cases in Sortment.

Connection configuration

Following details are requied on Sortment for S3 connection for Snowflake:

• AWS Region: The geographical region where your AWS services, including S3 and Snowflake, are deployed. Examples include us-east-1 (N. Virginia) or ap-south-1 (Mumbai). In your AWS Console → Click on your profile (top-right) → See the selected region.

• AWS S3 Bucket Name: A globally unique name assigned to an S3 bucket where you store and retrieve data. On AWS Console → Go to S3 → Locate your bucket under “Buckets” list.

• Access Key ID: A unique identifier for an AWS IAM user or service that allows programmatic access to AWS services. On AWS Console → IAM → Users → Select your user → Security Credentials tab → Generate Access Key.

• Secret Access Key: A secret key paired with the Access Key ID, used for signing API requests securely. Generated alongside the Access Key ID in IAM (only shown once). If lost, you must generate a new pair.

• Snowflake Stage Name: This stage will be used to read and write data between your Snowflake and Amazon S3 bucket. You have to create a new stage for Sortment, and use the resepctive name here. Follow the steps below to create the stage.

AWS credentials setup

Follow these steps to setup an S3 bucket for Sortment:

Creating a bucket

1. Sign in to the AWS Management Console and navigate to the S3 service.

2. Click on "Create bucket."

3. Enter a unique bucket name (globally unique across AWS).

4. Select an AWS region for the bucket. This should be same as your Snowflake cluster region.

5. Create the bucket.

Creating a user

Follow the user creation flow to create a new user for Sortment. If you need help, consult the IAM article on this topic.

Create inline policy to the user

1. From your AWS console navigate to Identity and Access Management (IAM) > Users > Select the user > Add permission > Create inline policy

2. In the JSON policy editor, use the following policy. Update {$bucket-name} to the bucket created above. Give your policy a name and create the policy.

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Effect": "Allow",
			"Action": "s3:*",
			"Resource": [
					"arn:aws:s3:::{$bucket-name}",
					"arn:aws:s3:::{$bucket-name}/*"
				]
		}
	]
}

Configuring Access Key

The Access Key access type allows you to configure Sortment to use an IAM user by providing the user's Access Key ID and Secret Access Key.

If you need help generating these keys, consult the IAM article on this topic.

Once you have an Access Key ID and Secret Access Key, paste those values into the form and click Create.

Creating Stage in Snowflake

Once the credentials are created, you need to create a stage in Snowflake to complete the S3 connection.

Ensure that the stage name is set as sortment.

-- Set variables
set bucket_url='s3://sortment';
set aws_key_id='REPLACE_WITH_YOUR_AWS_KEY';
set aws_secret_key='REPLACE_WITH_YOUR_AWS_SECRET_KEY';
set smt_default_role='SORTMENT_ROLE';

-- Set role for grants
USE ROLE identifier($smt_default_role);

-- Create stage for Sortment
CREATE OR REPLACE STAGE sortment
  URL=$bucket_url
  CREDENTIALS=(AWS_KEY_ID=$aws_key_id AWS_SECRET_KEY=$aws_secret_key)
  file_format = (type = csv field_optionally_enclosed_by='"' compression = none)

Setting up the credentials

Use the credentials generated above to connect Sortment to your S3 bucket and proceed.
