Snowflake Connection

Overview

To set up Warehouse Native connection with Snowflake, Statsig needs the following

• Account Name
• Database Name
• Schema Name
• Service User Name
• Service User Password

The service user needs the following permissions:

• READ on any tables you are using for experimentation
• USAGE/WRITE on a Statsig-specific Schema we'll use to materialize temp tables and results

Account Name

For the Account Name field, please enter in the format of <id>.<region>.<provider>. So, your information may look something like this:

xy12345.us-central1.gcp

To get this information navigate to bottom left in your Snowflake console, as shown in the picture below and copy the link URL:

The copied URL will look something like this:

https://xy12345.us-central1.gcp.snowflakecomputing.com

You can extract information from here to get the required fields for Account Name, which for this example would be xy12345.us-central1.gcp.

Using <orgname>-<account_name> for Account Name

For the Account Name field, you can also enter your Snowflake account identifier, which typically takes the form <orgname>-<account_name>. To find the <orgname> in the Snowflake console, click on your account profile (usually at the bottom left) to view account details as shown below.

Database and Schema Name

Provide the Schema and corresponding Database where Statsig will be able to materialize results

Boilerplate Setup SQL

To create a Statsig user with the sufficient privileges, as well as a Statsig staging Schema, run the following code in your Snowflake worksheet that has sysadmin and securityadmin roles.

Replace <USER> and <PASSWORD> with your value, which you will copy over into our console.

Depending on the scope of your data, you may want to adjust the size of the warehouse created.

BEGIN;
  -- set up variable values to be used in statements later
  -- make sure to configure user_name and user_password with your own values
  SET user_name = '<USERNAME>'; -- REPLACE WITH YOUR OWN VALUE
  SET user_password = '<PASSWORD>'; -- REPLACE WITH YOUR OWN VALUE
  SET role_name = 'STATSIG_ROLE';

  -- change role to sysadmin for warehouse / database steps
  USE ROLE sysadmin;

  -- create a warehouse, database, schema and tables for Statsig
  CREATE OR REPLACE WAREHOUSE STATSIG WITH warehouse_size='XLARGE'; -- adjust based on your data size
  CREATE DATABASE IF NOT EXISTS STATSIG_STAGING;
  CREATE SCHEMA IF NOT EXISTS STATSIG_STAGING.STATSIG_TABLES;

  -- change current role to securityadmin to create role and user for Statsig's access
  USE ROLE securityadmin;

  -- create role for Statsig
  CREATE ROLE IF NOT EXISTS identifier($role_name);
  GRANT ROLE identifier($role_name) TO ROLE SYSADMIN;

  -- create a user for Statsig
  CREATE USER IF NOT EXISTS identifier($user_name)
  password = $user_password
  default_role = $role_name
  default_namespace = STATSIG_STAGING.STATSIG_TABLES
  default_warehouse = STATSIG;
  GRANT ROLE identifier($role_name) TO USER identifier($user_name);

  -- grant Statsig role access to create warehouse and schema
  GRANT USAGE ON WAREHOUSE STATSIG TO ROLE identifier($role_name);
  GRANT USAGE ON SCHEMA STATSIG_STAGING.STATSIG_TABLES TO ROLE identifier($role_name);
  GRANT CREATE SCHEMA, MONITOR, USAGE ON DATABASE STATSIG_STAGING TO ROLE identifier($role_name);

  -- ONLY GIVE THIS LEVEL OF ACCESS in the staging schema.
  GRANT CREATE TABLE ON SCHEMA STATSIG_STAGING.STATSIG_TABLES TO ROLE identifier($role_name);
  GRANT SELECT, UPDATE, INSERT, DELETE ON ALL TABLES IN SCHEMA STATSIG_STAGING.STATSIG_TABLES TO ROLE identifier($role_name);
  GRANT SELECT, UPDATE, INSERT, DELETE ON FUTURE TABLES IN SCHEMA STATSIG_STAGING.STATSIG_TABLES TO ROLE identifier($role_name);
  GRANT OWNERSHIP ON FUTURE TABLES IN SCHEMA STATSIG_STAGING.STATSIG_TABLES TO ROLE identifier($role_name);

  -- grant Statsig role read access to database and schema passed in
  -- do this at a table level, database level, and/or schema level
  -- for data Statsig needs to access
  GRANT USAGE ON DATABASE <DATABASE> TO ROLE identifier($role_name);
  GRANT USAGE ON SCHEMA <DATABASE>.<SCHEMA> TO ROLE identifier($role_name);
  GRANT SELECT ON ALL TABLES IN DATABASE <DATABASE> TO ROLE identifier($role_name);
  GRANT SELECT ON FUTURE TABLES IN DATABASE <DATABASE> TO ROLE identifier($role_name);
  GRANT SELECT ON ALL VIEWS IN DATABASE <DATABASE> TO ROLE identifier($role_name);
  GRANT SELECT ON FUTURE VIEWS IN DATABASE <DATABASE> TO ROLE identifier($role_name);

COMMIT;
