Snowflake Prerequisites

Configuring your Snowflake destination.

Prerequisites

  • In order to complete the following setup steps, you or a Snowflake admin on your team must have the securityadmin and sysadmin roles. (To check your account for these roles, run SHOW GRANTS TO USER <your_username>; and review the role column.)

Step 1: Create role, user, warehouse, and database in the data warehouse

  1. Review and make any changes to the following setup script.
begin;
 
   -- create variables for user / password / role / warehouse / database
   set role_name = 'TRANSFER_ROLE'; -- all letters must be uppercase
   set user_name = 'TRANSFER_USER'; -- all letters must be uppercase
   set user_password = 'some_password'; -- alphanumeric only, special characters are not allowed
   set warehouse_name = 'TRANSFER_WAREHOUSE'; -- all letters must be uppercase
   set database_name = 'TRANSFER_DATABASE'; -- all letters must be uppercase

   -- change role to securityadmin for user / role steps
   use role securityadmin;
 
   -- create role for data transfer service
   create role if not exists identifier($role_name);
   grant role identifier($role_name) to role SYSADMIN; -- establish SYSADMIN as the parent of the new role. Note: this does not grant the access privileges of SYSADMIN to the new role.
 
   -- create a user for data transfer service
   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);
 
   -- change role to sysadmin for warehouse / database steps
   use role sysadmin;
 
   -- create a warehouse for data transfer service
   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 data transfer service
   create database if not exists identifier($database_name);
 
   -- grant service role access to warehouse
   grant USAGE
   on warehouse identifier($warehouse_name)
   to role identifier($role_name);
 
   -- grant service access to database
   grant CREATE SCHEMA, MONITOR, USAGE
   on database identifier($database_name)
   to role identifier($role_name);
 
 commit;

NOTE: special characters are not allowed for the password and might cause connection issues. We recommend using exclusively URL safe, alphanumeric characters.

📘 Using an existing warehouse or database

By default, this script creates a new warehouse and a new database. If you'd prefer to use an existing warehouse/database, change the warehouse_name variable from TRANSFER_WAREHOUSE to the name of the warehouse to be shared/database_name variable from TRANSFER_DATABASE to the name of the database to be shared.

  1. In the Snowflake interface, select the All Queries checkbox, and click "Run". This will run every query in the script at once. If successful, you will see Statement executed successfully in the query results.

Step 2: Configure the Snowflake access policy

If your Snowflake data warehouse is using Snowflake Access Policies, a new policy must be added to allow the transfer service static IP (34.171.168.215/32) to write to the warehouse.

  1. Review current network policies to check for existing IP safelists.
SHOW NETWORK POLICIES;
  1. If there is no existing Snowflake Network Policies (the SHOW query returns no results), you can skip to Step 3.
  2. If there is an existing Snowflake Network Policy, you must alter the existing policy or create a new one to safelist the data transfer service static IP address (34.171.168.215/32). Use the CREATE NETWORK POLICY command to specify the IP addresses that can access your Snowflake warehouse.
CREATE NETWORK POLICY <transfer_service_policy_name> ALLOWED_IP_LIST = ('34.171.168.215/32');

Creating your first network policy

If you have no existing network policies and you create your first as part of this step, all other IPs outside of the ALLOWED_IP_LIST will be blocked. Snowflake does not allow setting a network policy that blocks your current IP address. (An error message results while trying to create a network policy that blocks the current IP address.) But be careful when setting your first network policy.

Step 3: Gather the required setup information

For the data export setup you will need:

  • Hostname and database name of the destination Snowflake data warehouse
  • Username and password of the newly created user
  • If your Snowflake data warehouse is using Snowflake Access Policies, you will need to have the data-syncing service's static IP available as well.
    • To do so, use the following command:
      CREATE NETWORK POLICY <transfer_service_policy_name> ALLOWED_IP_LIST = ('34.171.168.215/32');
    • Note: If you have no existing network policies and you create your first as part of this step, all other IPs outside of the ALLOWED_IP_LIST will be blocked. Snowflake does not allow setting a network policy that blocks your current IP address. (An error message results while trying to create a network policy that blocks the current IP address.) But be careful when setting your first network policy.
