Snowflake Setup Guide

Follow our setup guide to connect your Snowflake data warehouse to Fivetran.

Prerequisites

To connect Snowflake to Fivetran, you need the following:

Snowflake account: A Snowflake account with a user role that has the permissions to create a user, role, and warehouse for Fivetran (such as the sysadmin or securityadmin roles).
Fivetran role: A Fivetran role with the Create Destinations or Manage Destinations permissions.
Collation requirements: The Snowflake data warehouse's collation must be capable of handling both case-sensitive and non-ASCII characters to ensure the integrity of your data.
Avoid applying custom collation to your account, database, schema, table, or column. Instead, use collation directly in your queries. Custom collation reduces the maximum column storage for strings from 16 MB to 8 MB, which can result in a String is too long to be compared using collation error if more than 8 MB of data is loaded into a column with collation enabled.
Snowflake configuration parameters:
- (Not applicable to Hybrid Deployment with Snowflake internal stage) The PREVENT_LOAD_FROM_INLINE_URL and REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_OPERATION parameters of the Snowflake data warehouse must be set to FALSE.
- If your Snowflake connection is configured to preserve source naming, the QUOTED_IDENTIFIERS_IGNORE_CASE parameter must be set to FALSE for Fivetran users.

In Snowflake, if you use double quotes around an identifier name, it makes the identifier name case-sensitive. We recommend using the create <identifier> <identifier_name> or the create <identifier> "IDENTIFIER_NAME" format. See Snowflake's documentation on identifiers for more information.

Setup instructions

Choose your deployment model

Before setting up your destination, decide which deployment model best suits your organization's requirements. This destination supports both SaaS and Hybrid deployment models, offering flexibility to meet diverse compliance and data governance needs.

See our Deployment Models documentation to understand the use cases of each model and choose the model that aligns with your security and operational requirements.

You must have an Enterprise or Business Critical plan to use the Hybrid Deployment model.

Choose Snowflake warehouse type

You can choose to create an exclusive warehouse for Fivetran or use an existing warehouse:

You can create and use an exclusive warehouse for Fivetran. Fivetran operations will never contend with your queries for resources. You will have to pay the cost of running the warehouse.
You can use a shared warehouse to reduce your warehouse running cost. Fivetran loads data incrementally and consumes very little compute resources. Fivetran operations may have to contend with your queries for the shared resources.

Run script in Snowflake warehouse

Copy the following script to a new worksheet:

begin;

   -- create variables for user / password / role / warehouse / database (needs to be uppercase for objects)
   set role_name = 'FIVETRAN_ROLE';
   set user_name = 'FIVETRAN_USER';

   -- we recommend removing the following line because Snowflake is planning to discontinue password-based authentication
   set user_password = 'password123';

   set warehouse_name = 'FIVETRAN_WAREHOUSE';
   set database_name = 'FIVETRAN_DATABASE';

   -- change role to securityadmin for user / role steps
   use role securityadmin;

   -- create role for fivetran
   create role if not exists identifier($role_name);
   grant role identifier($role_name) to role SYSADMIN;

   -- create a user for fivetran
   create user if not exists identifier($user_name)
   password = $user_password
   default_role = $role_name
   default_warehouse = $warehouse_name;

   grant role identifier($role_name) to user identifier($user_name);

   -- set binary_input_format to BASE64
   ALTER USER identifier($user_name) SET BINARY_INPUT_FORMAT = 'BASE64';

   -- change role to sysadmin for warehouse / database steps
   use role sysadmin;

   -- create a warehouse for fivetran
   create warehouse if not exists identifier($warehouse_name)
   warehouse_size = xsmall
   warehouse_type = standard
   auto_suspend = 60
   auto_resume = true
   initially_suspended = true;

   -- create database for fivetran
   create database if not exists identifier($database_name);

   -- grant fivetran role access to warehouse
   grant USAGE
   on warehouse identifier($warehouse_name)
   to role identifier($role_name);

   -- grant fivetran access to database
   grant CREATE SCHEMA, MONITOR, USAGE
   on database identifier($database_name)
   to role identifier($role_name);

   -- change role to ACCOUNTADMIN for STORAGE INTEGRATION support (only needed for Snowflake on GCP)
   use role ACCOUNTADMIN;
   grant CREATE INTEGRATION on account to role identifier($role_name);
   use role sysadmin; 
   
 commit;

Depending on whether you want to create a new warehouse or use a shared warehouse do either:
- If you want to create a new exclusive warehouse, don't make any changes to the FIVETRAN_WAREHOUSE value in the script.
- If you want Fivetran to use a shared warehouse to ingest data, change the FIVETRAN_WAREHOUSE value in the script to the name of the shared warehouse.
Replace the default FIVETRAN_ROLE, FIVETRAN_DATABASE, and FIVETRAN_USER values with values that conform to your specific naming conventions for those resources.
Do not use this username for any other purpose.
Make a note of the values that replace the default FIVETRAN_DATABASE and FIVETRAN_USER values. You will need them to configure Fivetran.
Depending on the type of Snowflake user you want to create for Fivetran, do one of the following:
- If you want to create a PERSON or NULL user (default user), replace the default value of user_password (password123) in the script with a value of your choice and make a note of the updated value.
  We recommend using key-pair authentication because Snowflake is planning to discontinue password-based authentication.
- If you want to create a SERVICE user, delete set user_password = 'password123'; from the script and replace password = $user_password in the script with TYPE = SERVICE.
  You must configure key-pair authentication for SERVICE users.
Depending on the Snowflake interface you are using, do one of the following:
- Classic web interface: Select the All Queries checkbox.
- Snowsight: Select the text of all queries in the query editor.
Run the script.

Configure key-pair authentication

This step is mandatory if you modified the script to create a SERVICE user for Fivetran.

Open the command line in a terminal window.
Generate a private key. You can generate an encrypted version of the private key or an unencrypted version of the private key.
- To generate an unencrypted version, you can execute one of the following commands:
  - openssl genrsa -out rsa_key.pem 2048
  - openssl genrsa 2048 | openssl pkcs8 -topk8 -inform PEM -out rsa_key.p8 -nocrypt
- To generate an encrypted version, execute the command openssl genrsa 2048 | openssl pkcs8 -topk8 -v1 <ALGORITHM> -inform PEM -out rsa_key.p8. You can use different algorithms with the -v1 command line option. These algorithms use the PKCS#12 password-based encryption algorithm and allow you to use strong encryption algorithms like triple DES or 128-bit RC2. You can use the following encryption algorithms:
  - PBE-SHA1-RC2-40
  - PBE-SHA1-RC4-40
  - PBE-SHA1-RC2-128
  - PBE-SHA1-RC4-128
  - PBE-SHA1-3DES
  - PBE-SHA1-2DES
- To use stronger encryption algorithms, execute the command openssl genrsa 2048 | openssl pkcs8 -topk8 -v2 <ALGORITHM> -inform PEM -out rsa_key.p8. You can use different algorithms with the -v2 command line option. You can use the following encryption algorithms:
  - AES128
  - AES256
  - DES3
From the command line, generate the public key by referencing the correct version of your generated private key. You can execute one of the following commands:
- If you used the openssl genrsa -out rsa_key.pem 2048 command to create the private key, run the openssl rsa -in rsa_key.pem -pubout -out rsa_key.pub command to create the public key.
- If you used the openssl genrsa 2048 | openssl pkcs8 -topk8 -inform PEM -out rsa_key.p8 -nocrypt command to create the private key, then run the openssl rsa -in rsa_key.p8 -pubout -out rsa_key.pub command to create the public key.
Assign the public key to the Snowflake user. In a Snowflake worksheet, execute the command alter user <USERNAME> set rsa_public_key='<PUBLIC_KEY>';.
You must have the sysadmin or securityadmin role to execute this command.

(Optional) Configure external storage for Hybrid Deployment

This is a mandatory step only for the Hybrid Deployment model. Skip to the next step if you want to use the SaaS Deployment model.

In the Hybrid Deployment model, we temporarily stage your data in an external storage location before writing it to your Snowflake destination.

We support the following storage services for staging your data:

Snowflake internal stage: Stores your data in Snowflake's user stage. By default, we use this storage for staging your data. To use Snowflake's internal stage, you do not have to configure anything. We will use the default user stage associated with your Snowflake account.
Amazon S3: Stores your data in an S3 bucket.
Azure Blob Storage: Stores your data in an Azure Blob Storage container.
Google Cloud Storage: Stores your data in a Google Cloud Storage bucket.

Configure Amazon S3 bucket

Create S3 bucket

Create an S3 bucket by following the instructions in AWS's documentation.

Your S3 bucket and Snowflake account must be in the same region.

Create IAM policy for S3 bucket

Open your Amazon IAM console.
Go to Policies, and then click Create policy.
Go to the JSON tab.

Copy the following policy and paste it in the JSON editor.

{
    "Version": "2012-10-17",
    "Statement": [
        {
        "Sid": "VisualEditor0",
        "Effect": "Allow",
        "Action": [
            "s3:DeleteObjectTagging",
            "s3:ReplicateObject",
            "s3:PutObject",
            "s3:GetObjectAcl",
            "s3:GetObject",
            "s3:DeleteObjectVersion",
            "s3:ListBucket",
            "s3:PutObjectTagging",
            "s3:DeleteObject",
            "s3:PutObjectAcl"
        ],
        "Resource": [
            "arn:aws:s3:::{your-bucket-name}/*",
            "arn:aws:s3:::{your-bucket-name}"
        ]
        }
    ]
}

In the policy, replace {your-bucket-name} with the name of your S3 bucket.
Click Next.
Enter a Policy name.
Click Create policy.

(Optional) Configure IAM role authentication

Perform this step only if you want us to use AWS Identity and Access Management (IAM) to authenticate requests in your S3 bucket. Skip to the next step if you want to use IAM user credentials for authentication.
To authentication using IAM, your Hybrid Deployment Agent must run on an EC2 instance in the account associated with your S3 bucket.

In the Amazon IAM console, go to Roles, and then click Create role.
Select AWS service.
In Service or use case drop-down menu, select EC2.
Click Next.
Select the checkbox for the IAM policy you created for your S3 bucket.
Click Next.
Enter the Role name and click Create role.
In the Amazon IAM console, go to the EC2 service.
Go to Instances, and then select the EC2 instance hosting your Hybrid Deployment Agent.
In the top right corner, click Actions and go to Security > Modify IAM role.
In the IAM role drop-down menu, select the new IAM role you created and click Update IAM role.

(Optional) Configure IAM user authentication

Perform this step only if you want us to use IAM user credentials to authenticate requests in your S3 bucket.

In the Amazon IAM console, go to Users, and then click Create user.
Enter a User name, and then click Next.
Select Attach policies directly.
Select the checkbox next to the policy you create in the Create IAM policy for S3 bucket step, and then click Next.
In the Review and create page, click Create user.
In the Users page, open the user you created.
Click Create access key.
Select Application running outside AWS, and then click Next.
Click Create access key.
Click Download .csv file to download the Access key ID and Secret access key to your local drive. You will need them to configure Fivetran.

Configure Azure Blob storage container

Create Azure storage account

Create an Azure storage account by following the instructions in Azure Blob Storage's documentation. While creating the account, make sure you do the following:
- In the Advanced tab:
  - select the Require secure transfer for REST API operations and Enable storage account key access checkboxes.
  - in the Permitted scope for copy operations drop-down menu, select From any storage account.
- In the Networking tab, select one of the following Network access options:
  - If your Snowflake destination is not hosted on Azure or if your storage container and destination are in different regions, select Enable public access from all networks.
  - If your Snowflake destination is hosted on Azure and if it is in the same region as your storage container, select Enable public access from selected virtual networks and IP addresses.
- In the Encryption tab, choose Microsoft-managed keys (MMK) as the Encryption type.
If you selected Enable public access from selected virtual networks and IP addresses as the Network access option in Step 1, do the following:
i. Log in to your Snowflake account and run the following commands to get your Snowflake VNet subnet ID:
```
USE ROLE ACCOUNTADMIN;
SELECT SYSTEM$GET_SNOWFLAKE_PLATFORM_INFO();
```
ii. Log in to your Azure account using Azure CLI and run the following command:
```
az storage account network-rule add --resource-group "<your_resource_group>" --account-name "<your_storage_account>" --subnet <your_snowflake_vnet_subnet_id>
```
Before running the command, replace <your_resource_group> with your Azure resource group name, <your_storage_account> with your Azure storage account name, and <your_snowflake_vnet_subnet_id> with your Snowflake VNet subnet ID.
iii. Log in to the Azure portal.
iv. Go to your storage account.
v. On the navigation menu, click Networking under Security + networking.
vi. Go to the Firewall section.
vii. In the Address range field, enter the IP address of the machine that hosts your Hybrid Deployment Agent.
viii. Click Save.

Find storage account name and access key

Log in to the Azure portal.
Go to your storage account.
On the navigation menu, click Access keys under Security + networking.
Make a note of the Storage account name and Key. You will need them to configure Fivetran.
As a security best practice, do not save your access key and account name anywhere in plain text that is accessible to others.

Configure Google Cloud Storage bucket

Create Google Cloud Storage bucket

Create a Google Cloud Storage (GCS) bucket by following the instructions in GCS's documentation.
Your GCS bucket and Snowflake account must be in the same region.
Make a note of the bucket name. You will need it to configure Fivetran.

Create service account and private key

Create a service account to provide Fivetran access to the GCS bucket you created in the previous step.

Create a private service account key in JSON format for the new service account you created in Step 1. The private key must be in the following format:

{
  "type": "service_account",
  "project_id": "<project_id>",
  "private_key_id": "<key_id>",
  "private_key": "*****",
  "client_email": "name@project.iam.gserviceaccount.com",
  "client_id": "<client_id>",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/name%40project.iam.gserviceaccount.com"
}

Keep the JSON file in a secure location. You will need it to configure Fivetran.

Assign permissions to service account

Log in to the Google Cloud console.
Go to Storage > Browser.
Select the bucket you want to use.
Go to the Permissions tab and then click Add Principals.
Specify the service account you created.
In the Select a role drop-down menu, select Storage Object Admin.
Click Save.

Add object lifecycle rule

In your Google Cloud console, go to Storage > Browser.
Find and select the bucket you are using for Fivetran.
In the Lifecycle rules column, select its rules.
Click ADD A RULE. A detail view will open.
In the Select an action section, select Delete object.
Click CONTINUE.
In the Select object conditions section, select the Age checkbox and then enter 1.
Click CONTINUE and then click CREATE.

(Optional) Configure external storage for unstructured files

By default, Fivetran lands unstructured files in a Snowflake Named internal stage.

Fivetran also supports Amazon S3 and Google Cloud Storage as external stages to land unstructured files using a Snowflake storage integration.

Configure Amazon S3 bucket as external stage

Create S3 bucket

Create an S3 bucket by following the instructions in AWS's documentation.

Create IAM policy for S3 bucket

Open your Amazon IAM console.
Go to Policies, and then click Create policy.
Go to the JSON tab.

Copy the following policy and paste it in the JSON editor.

 {
    "Version": "2012-10-17",

            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:GetObjectVersion",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion"
            ],
            "Resource": "arn:aws:s3:::{your-bucket-name}/{your-folder-path}/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket",
                "s3:GetBucketLocation"
            ],
            "Resource": "arn:aws:s3:::{your-bucket-name}"
        }
    ]
}

In the policy above, replace {your-bucket-name} with the name of your S3 bucket and {your-folder-path} with path of the folder where you want to store External Stage files.
Click Next.
Enter a Policy name.
Click Create policy.

Create IAM role

In the Amazon IAM console, go to Roles, and then click Create role.
Select AWS account.
In An AWS account section, select Another AWS account.
Specify your Fivetran Account ID 834469178297
Click Next.

Enter the Role name and click Create role.

Create Amazon S3 storage integration

Copy the following queries in a worksheet:

CREATE STORAGE INTEGRATION IF NOT EXISTS '{storage-integration-name}'
  TYPE = EXTERNAL_STAGE
  STORAGE_PROVIDER = 'S3'
  STORAGE_AWS_ROLE_ARN = '{your-role-arn}'
  STORAGE_AWS_EXTERNAL_ID = '{your-external-id}'
  ENABLED = TRUE
  STORAGE_ALLOWED_LOCATIONS = ('s3://{your-bucket-name}/{your-folder-path}/' );

GRANT USAGE ON INTEGRATION '{storage-integration-name}' TO ROLE '{role}';
DESC STORAGE INTEGRATION '{storage-integration-name}';

In the queries, replace following placeholders:
- {storage-integration-name} with the name of your Storage Integration
- {your-role-arn} with the ARN of the IAM role you created in the Create IAM role step.
- {your-external-id} with a custom External ID. Generate a random External ID.
- {your-bucket-name} with the name of your S3 bucket
- {your-folder-path} with path of the folder where you want to store External Stage files.
- {role} with the role you created in the Run script in Snowflake warehouse step.
Execute the query and make a note of the STORAGE_AWS_IAM_USER_ARN & STORAGE_AWS_EXTERNAL_ID. You will need it to create a trusted policy.

Configure trust policy

In the Amazon IAM console, go to Roles, and then open role created in the Create IAM role step.
Go to the Trust relationships tab.
Click Edit trust policy.

Copy the following policy and paste it in the JSON editor.

{
    "Version": "2012-10-17",
    "Statement": [

            "Principal": {
                "AWS": [
                    "arn:aws:iam::834469178297:root",
                    "{snowflake-aws-iam-user-arn}"
                ]
            },
            "Action": "sts:AssumeRole",
            "Condition": {
                "StringEquals": {
                    "sts:ExternalId": "{external-id}"
                }
            }
        }
    ]
}

In the policy above, replace {snowflake-aws-iam-user-arn} and {external-id} with the values of STORAGE_AWS_IAM_USER_ARN and STORAGE_AWS_EXTERNAL_ID you noted earlier.
Click Update policy.

Configure GCS bucket as external stage

Create a GCS bucket.
Create a GCS storage integration.
Execute the following command: DESC STORAGE INTEGRATION <integration_name>.
Give permissions for the Snowflake service account to access the GCS bucket.
Give the Storage Object Admin permission to the Fivetran service account (you found in the setup form) to access the GCS bucket. We need this permission to access the bucket to add and delete objects to match the source data.

(Optional) Connect using AWS PrivateLink, Azure Private Link, or Google Cloud Private Service Connect

You can connect Fivetran to your Snowflake destination using either AWS PrivateLink, Azure Private Link, or Google Cloud Private Service Connect. Fivetran uses your chosen service to move your data securely between our system and your Snowflake destination.

Connect using AWS PrivateLink

AWS PrivateLink allows VPCs and AWS-hosted or on-premises services to communicate with one another without exposing traffic to the public internet. PrivateLink is the most secure connection method. Learn more in AWS’ PrivateLink documentation.

Prerequisites

To set up AWS PrivateLink, you need a Business Critical Snowflake account in one of our supported regions.

Postrequisites

To use AWS PrivateLink, you must select AWS as a Cloud service provider in the Complete Fivetran configuration step.

Configure AWS PrivateLink for Snowflake destination

Contact Snowflake Support and tell them that you want to enable AWS PrivateLink for Fivetran. Provide the following information:
- Fivetran’s AWS VPC Account ID: arn:aws:iam::834469178297:root
- Your Snowflake account URL
Once Snowflake receives this information, they will allow Fivetran to establish a private link connection to your Snowflake destination.
Snowflake will provide you with a VPCe in the format com.amazonaws.vpce.<region_id>.vpce-svc-xxxxxxxxxxxxxxxxx. Make a note of this VPCe. You will need it later.
Go to your Snowflake instance and execute the following query:
SELECT SYSTEM$GET_PRIVATELINK_CONFIG();

Send the VPCe you found in Step 2 and the output of the query to your Fivetran account manager. The output will be in the following format:

{
   "privatelink-account-name": "<account_name>",
   "privatelink-account-url": "<privatelink_account_url>",
   "privatelink-ocsp-url": "<privatelink_ocsp_url>",
   "privatelink-vpce-id": "<aws_vpce_id>"
}

Notify your Fivetran account manager that you have completed these steps. We then finish setting up PrivateLink for your Snowflake destination on our side. Once the setup is complete, we send you the host address and resource ID for your PrivateLink connection.
Make a note of the host address that you received from Fivetran. You need it to configure Fivetran.
Contact Snowflake Support and provide the resource ID (also known as the vpc_endpoint_id) that you received from Fivetran.

Connect using Azure Private Link

Azure Private Link allows VNet and Azure-hosted or on-premises services to communicate with one another without exposing traffic to the public internet. Learn more in Microsoft's Azure Private Link documentation.

Prerequisites

To set up Azure Private Link, you need a Snowflake account hosted in Azure.

Postrequisites

To use Azure PrivateLink, you must select Azure as a Cloud service provider in the Complete Fivetran configuration step.

Configure Azure Private Link for Snowflake destination

Contact Snowflake Support and tell them that you want to enable Azure Private Link for your Snowflake instance and Snowflake internal stage to connect Fivetran. Provide the following information:
- Fivetran’s Azure subscription ID: 6d755170-32cd-4a50-8bf2-621c984f3528
- Your Snowflake account URL
Once Snowflake receives this information, they will allow Fivetran to establish a private link connection to your Snowflake destination and Snowflake internal stage.
Once Snowflake has approved your request, go to your Snowflake instance and execute the following query as a user with the Snowflake ACCOUNTADMIN role to obtain the URL that we need to access Snowflake through Azure Private Link:
SELECT SYSTEM$GET_PRIVATELINK_CONFIG();

Send the output of the query to your Fivetran account manager. The output will be in the following format:

{
  "privatelink-account-name": "<account_identifier>",
  "privatelink-internal-stage": "<privatelink_stage_endpoint>",
  "privatelink-account-url":"<privatelink_account_url>",
  "privatelink-ocsp-url": "<privatelink_ocsp_url>",
  "privatelink-pls-id": "<azure_privatelink_service_id>"
}

We then finish setting up Private Link for your Snowflake destination on our side. Once the setup is complete, we send you the host address and the resource ID for your Private Link connection.

Make a note of the host address that you received from Fivetran. You need it to configure Fivetran.
Contact Snowflake Support and provide the resource ID (also known as the private_endpoint_id) that you received from Fivetran.

For more information, see How to set up Privatelink to Snowflake from 3rd party Cloud Service vendors.

Connect using Google Cloud Private Service Connect

Google Cloud Private Service Connect allows VPCs and Google-hosted or on-premises services to communicate with one another without exposing traffic to the public internet. Learn more in Google Cloud's Private Service Connect documentation.

Prerequisites

To set up Google Cloud Private Service Connect, you need a Business Critical Snowflake account in one of our supported regions.

Postrequisites

To use Google Cloud Private Service Connect, you must select GCP as a Cloud service provider in the Complete Fivetran configuration step.

Configure Google Cloud Private Service Connect for Snowflake destination

Follow the instructions in Snowflake's Google Cloud Private Service Connect & Snowflake documentation. When contacting Snowflake Support, tell them that you want to enable Google Cloud Private Service Connect for Fivetran. Provide the following information:
- Fivetran’s project id: fivetran-donkeys
- Your Snowflake account URL
Once Snowflake receives this information, they will allow auto-approval for Fivetran’s project.
Once Snowflake has approved your request, go to your Snowflake instance and execute the following query as a user with the Snowflake ACCOUNTADMIN role to obtain the URL that we need to access Snowflake through Google Cloud Private Service Connect:
SELECT SYSTEM$GET_PRIVATELINK_CONFIG();
Send the output of the query to your Fivetran account manager. The output will be in the following format:
```
{
  "privatelink-account-name": "<account_identifier>",
  "privatelink-account-url":"<privatelink_account_url>",
  "privatelink-ocsp-url": "<privatelink_ocsp_account_url>",
  "privatelink-gcp-service-attachment": "<privatelink_service_attachment_id>"
}
```
We then finish setting up Private Service Connect for your Snowflake destination on our side. Once the setup is complete, we send you the host address and the Resource ID (also known as the psc_connection_id).
Make a note of the host address that you received from Fivetran. You need it to configure Fivetran.
If you need to troubleshoot your connection with Snowflake Support, be sure to provide your Private Service Connection ID.

(Optional) Configure Snowflake network policy

If you have defined a Snowflake Network Policy, update your Snowflake Network Policy to add Fivetran IP address CIDRs or VPC IDs from one of the following sections.

Without AWS PrivateLink, Azure Private Link, or Google Cloud Private Service Connect

If you haven't configured AWS PrivateLink, Azure Private Link, or Google Cloud Private Service Connect connectivity, add Fivetran's IP addresses to your network policy's allowed list to allow connections from Fivetran.

With AWS PrivateLink

If you have configured AWS Private Link, add Fivetran's internal VPC CIDR range to the Snowflake network policy's allowed list: 10.0.0.0/8.

Alternatively, add the Fivetran VPC Endpoint ID (or AWS VPCE ID) to your network policy's allowed list.

Contact our support team and provide the name of the PrivateLink for the corresponding for the Fivetran VPC Endpoint ID (or AWS VPCE ID).

With Azure Private Link

If you have configured Azure Private Link, add Fivetran's internal VNet CIDR range to the Snowflake network policy's allowed list: 10.0.0.0/8.

Alternatively, add the Fivetran Resource ID (or Azure LinkID) to your network policy's allowed list.

Contact our support team and provide the name of the Private Link for the corresponding Fivetran Fivetran Resource ID (or Azure LinkID).

With Google Cloud Private Service Connect

If you have configured Google Cloud Private Service Connect, add Fivetran's internal VPC CIDR range to the Snowflake network policy's allowed list: 10.0.0.0/8.

(Optional) Configure failover

You must have a Snowflake Business Critical account or higher to use failover. Learn more in Snowflake's failover documentation.

Since Fivetran supports using Snowflake Client Redirect, you can set up database failover for Snowflake if you'd like. To configure failover in Snowflake, you must have two Snowflake accounts in two different regions. You must also have an account with the ORGADMIN role to add the accounts to a Snowflake organization and navigate between them.

Alternatively, you could have one Snowflake account and one organization account if you have the ACCOUNTADMIN role. To enable failover for the organization account, run the following command as the ORGADMIN:

USE ROLE ORGADMIN;
SELECT system$global_account_set_parameter('<org-name>.<org-account-itself>', 'ENABLE_ACCOUNT_DATABASE_REPLICATION', 'true');

In either case, do the following to set up failover:

If you haven't already, replicate your database. Follow the setup instructions in Snowflake's Replicating Databases Across Multiple Accounts documentation.
Enable failover for your primary database to your secondary database. Follow the setup instructions in Snowflake's Enable Replication for Accounts in the Organization documentation.
Set up Client Redirect to generate a single global URL that automatically points to the current primary account. Follow the setup in Snowflake's Configuring Client Redirect documentation.

Provide your Snowflake Client Redirect URL in the Host section of your setup form to ensure that Fivetran always points to the active account in case of failover.

Complete Fivetran configuration

Log in to your Fivetran account.
Go to the Destinations page and click Add destination.
Enter a Destination name of your choice and then click Add.
Select Snowflake as the destination type.
(Enterprise and Business Critical accounts only) Select the deployment model of your choice:
- SaaS Deployment
- Hybrid Deployment
If you choose Hybrid Deployment, select an existing Hybrid Deployment Agent in the Select an existing agent drop-down menu or configure a new agent.
For more information about configuring a new agent, see our Hybrid Deployment setup guides.
(Hybrid Deployment only) Select the external storage you configured to stage your data.
Depending on the external storage you selected, do the following:
i. If you selected Snowflake Internal Stage, skip to the next step.
ii. If you selected AWS S3, select the Authentication type (IAM ROLE or IAM USER) you configured for your S3 bucket, and then enter your S3 bucket's name and region.
iii. If you selected Azure Blob Storage, enter your storage account name and storage account key.
iv. If you selected Google Cloud Storage, upload the JSON file containing the service account key and enter the GCS bucket name.
(Not applicable to Hybrid Deployment) In the Connection Method drop-down menu, select how you want Fivetran to connect to your destination.
- Connect directly
- Connect via PrivateLink
The Connect via PrivateLink option is available only for Business Critical accounts.
If you selected Connect via PrivateLink as the connection method, select an existing PrivateLink connection, or create a new AWS PrivateLink or Azure Private Link connection.
If you selected Connect directly as the connection method or if you choose Hybrid Deployment as the deployment model, enter the host name or IP address of the database server in the Host field.
If you're using database failover, enter the Snowflake Client Redirect URL in the Host field to ensure that Fivetran always points to the active account in case of failover. If you use AWS PrivateLink or Azure Private Link, the URL format is <org-name>-<conn-name>.privatelink.snowflakecomputing.com. If you don't, the URL format is <org-name>-<conn-name>.snowflakecomputing.com.
Enter the User and Database names you found in Step 2.
Choose your authentication mode: KEY-PAIR or PASSWORD. See the steps for key-pair authentication.
- If you selected PASSWORD, enter the Password you found in Step 3.
- If you selected KEY-PAIR, enter the Private key. The private key cannot have spaces and must be prefixed by -----BEGIN PRIVATE KEY----- and postfixed by -----END PRIVATE KEY-----.
If you use an encrypted private key, set the Is Private Key encrypted toggle to ON, then enter your Passphrase. For OpenSSL versions older than 1.0, encrypted private keys must be prefixed by -----BEGIN RSA PRIVATE KEY----- and postfixed with -----END RSA PRIVATE KEY-----.
(Optional) If you want Fivetran to use a specific role instead of your default role, enter the Role name.
(Optional) In the Storage for Unstructured Files drop-down menu, select a storage integration. If you select an external storage integration such as GCS or S3, do the following:
1. In the Storage Integration field, enter the name of the integration you created.
2. In the Parent Folder Path field, enter the URI of the folder where External Stage files should be stored.
  Ensure that this folder is accessible to both the IAM role created in the Create IAM Role step and the storage integration set up in the Create Storage Integration step.
3. (Optional) For GCS, copy the service account email and provide the Storage Object Admin permission to the service account on the GCS bucket.
(Not applicable to Hybrid Deployment) Choose the Data processing location. Depending on the plan you are on and your selected cloud service provider, you may also need to choose a Cloud service provider and cloud region as described in our Destinations documentation.
If you are using AWS PrivateLink, Azure Private Link, or Google Cloud Private Connect Service, select the corresponding Cloud service provider.
Choose your Timezone.
(Optional for Business Critical accounts and SaaS Deployment) To enable regional failover, set the Use Failover toggle to ON, and then select your Failover Location and Failover Region. Make a note of the IP addresses of the secondary region and safelist these addresses in your firewall.
Click Save & Test.

Fivetran tests and validates the Snowflake connection. On successful completion of the setup tests, you can sync your data using Fivetran connections to the Snowflake destination.

In addition, Fivetran automatically configures a Fivetran Platform Connector to transfer the connection logs and account metadata to a schema in this destination. The Fivetran Platform Connector enables you to monitor your connections, track your usage, and audit changes. The connection sends all these details at the destination level.

If you are an Account Administrator, you can manually add the Fivetran Platform Connector on an account level so that it syncs all the metadata and logs for all the destinations in your account to a single destination. If an account-level Fivetran Platform Connector is already configured in a destination in your Fivetran account, then we don't add destination-level Fivetran Platform Connectors to the new destinations you create.

Setup tests

Fivetran performs the following Snowflake connection tests:

The Host Connection test checks the accessibility of the host and validates the database credentials you provided in the setup form.
The Validate Passphrase test validates your private key against the passphrase if you are using key-pair authentication.
The Default Warehouse test checks if the Snowflake data warehouse exists and if you have set it as the default warehouse.
The Database Connection test checks if we can connect to your Snowflake database.
The Permission test checks if we have the CREATE SCHEMA and CREATE TEMPORARY TABLES permission on your Snowflake database.
The Validate Privileges On Integration test checks if the default role assigned to the Fivetran user account has the required permissions on the storage integration. Fivetran performs this test only if your Snowflake data warehouse is hosted on Google Cloud Platform (GCP).
If you are setting up a new destination in the Hybrid Deployment model, the Validate Privileges On Integration test will fail for the first time. To resolve this, retrieve the cloud storage service account for your Snowflake account and grant the service account permissions to access bucket objects, and then click Save & Test again.
