Snowflake Integration

Euno's Snowflake integration supports auto-discovery of:

• Snowflake Views

• Usage information of applications using Snowflake, like Tableau

Setting up Snowflake integration

Required Snowflake Permissions

In order to integrate with Euno, create a custom role in Snowflake with the permissions listed below. In the code snippet below, we create a user euno_user, with password and a role euno_role.

Euno discovers Snowflake resources by issuing SQL queries on Snowflake's system database and information schema. The Snowflake role require the Snowflake USAGE grant on a Snowflake warehouse. In the code snippet below, we use the warehouse euno_dwh.

CREATE ROLE euno_role;
CREATE USER euno_user PASSWORD='euno_password' DEFAULT_ROLE='euno_role';
GRANT ROLE euno_role TO USER euno_user;
GRANT USAGE ON WAREHOUSE euno_dwh TO ROLE euno_role;
GRANT DATABASE ROLE SNOWFLAKE.OBJECT_VIEWER TO ROLE euno_role;
GRANT DATABASE ROLE SNOWFLAKE.GOVERNANCE_VIEWER TO ROLE euno_role;

Setup Steps

To integrate a Snowflake account please follow the below steps:

1	Click on the "Account settings" found in the left side menu.
2	Locate the Snowflake tile under the Integrations tab and click “Configure”.
3	Fill out the integration configuration. See integration configuration section below.
4	Your Snowflake integration is now configured. To add another instance, click on “Add account” and repeat step 3.

Integration Configuration

Asterik (*) means a mandatory field.

Configuration	Description
Host*	This is the Snowflake host associated with your Snowflake account. Below are some examples of Snowflake hosts: - mycompany.eu-central-1.snowflakecomputing.com - org-account.us-west-2.snowflakecomputing.com
Username*	The Snowflake user to use for the integration
Password*	The password of the Snowflake user for the integration
Role	The Snowflake role to use. If you configured the Snowflake user to have a default role, you can keep this blank.
Warehouse	The Snowflake warehouse to use for queries. If you configured the Snowflake user to have a default warehouse, you can keep this blank.
Table to use for query history	By default, Euno uses the table snowflake.account_usage.query_history to access your Snowflake's query history. If you prefer to use a different table, enter it here. See "Using a non-default query history view" below.
Skip SSL certificate verification	Skip SSL certificate verification. This is used in cases where Euno accessess Snowflake through a proxy. We recommend leaving this unchecked.
Use Snowflake system database to query for Snowflake views	By default, Euno uses the system view snowflake.account_usage.views to discover all Snowflake views defined in the snowflake account. If you prefer not to grant the integration permission for this system view, and instead have Euno iterate over all databases it has access to and query their information_schema, then uncheck this box.

Using a non-default query history view

By default, Euno uses the system view snowflake.account_usage.query_history to discover the query history.

You might prefer, for security reasons, to limit the rows or columns that Euno integration has access to.

In that case, you can manually create a Snowflake view to expose a subset of the query hisotry. In order for Euno to use this non-default Snowflake view, the following columns, available in snowflake.account_usage.query_history, must be exposed by the view:

• query_tag

• total_elapsed_time

• bytes_scanned

• start_time

• end_time

• query_type

Make sure you grant Euno permissions to SELECT on this view. Below is an example of creating such a view, and excluding records that were initiated by the user PRIVATE_USER

CREATE OR REPLACE VIEW user.public.query_history_for_euno AS (
  SELECT query_tag, total_elapsed_time, start_time, end_time, bytes_scanned, query_type
  FROM snowflake.account_usage.query_history
  WHERE user_name != 'PRIVATE_USER'
);

GRANT SELECT ON VIEW user.public.query_history_for_euno TO ROLE euno_role;

Discovered Resources

The Euno-Snowflake integration discovers the following resources:

Snowflake views

Property	Value
name	The name of the Snowflake view. This does not include the database or schema. So, for example, if the full name of the view is some_database.some_schema.some_view, then Euno will set the name to some_view
type	always table
database technology	always snowflake
materialized	false
schema	the name of the snowflake schema this table is in. For example, for the view some_database.some_schema.some_view, this will be set to some_schema.
database	the name of the snowflake schema this table is in. For example, for the view some_database.some_schema.some_view, this will be set to some_database.
created at	the time this view was created
updated at	the time this view's definition was last updated
description	If the view has a COMMENT, then it will be used as the description
owner	The Snowflake users set as the owner of the view
