For more about Secure Data Sharing, please see Snowflake’s official documentation.
Before initiating the sharing process with Kumo, please ensure the following: 1. Provider Sharing is Enabled
  • Log into your Snowflake account.
  • Navigate to Account > Policies.
  • Ensure Provider Sharing is set to Enabled. If not, activate it.
2. Identify Your Snowflake Account’s Region Data sharing is most straightforward when provider and consumer accounts are in the same Snowflake region. If they are in different regions, the data provider needs to use Snowflake’s “Data Replication” to replicate the data to the region where the consumer account resides before sharing. Kumo does not recommend Data Replication. Kumo has accounts in most of the global regions. Access the Snowflake web interface—your account’s region will be displayed in the top right corner, next to the account name (e.g., us-west-2). Remember to share with Kumo’s account in the corresponding region because secure share is only allowed with accounts in the same cloud and region.

​
Identify Your Snowflake Account Edition

The “Secure Data Sharing” feature is available in all editions of Snowflake, including Standard, Enterprise, Business Critical, and Virtual Private Snowflake (VPS). Thus, an account using the Standard edition can share data with an account using the Enterprise edition and vice versa. An account on the BUSINESS CRITICAL edition is restricted from sharing data with an account on a lower edition. Role Permissions The role used to create the share must have the necessary permissions on the objects being shared.

​
Creating a Snowflake Secure Share for Kumo

You can use Snowflake Secure Shares to share data with Kumo. This allows you to share the following Database objects (see https://docs.snowflake.com/en/user-guide/data-sharing-intro for more details):
  • Tables
  • External tables
  • Secure views
  • Secure materialized views
1. Establishing the Share Create a share: Use the CREATE SHARE command to create an empty share. For example: 
CREATE SHARE KUMO_SHARE;
Use the GRANT <privilege> … TO SHARE command to add a database to the share and then selectively grant access to specific database objects (schemas, tables and secure views) to the share. For example: 
GRANT USAGE ON DATABASE my_database TO SHARE kumo_share;
GRANT SELECT ON TABLE my_database.my_table TO SHARE kumo_share;
GRANT USAGE on schema my_database.myschema TO SHARE kumo_share;
GRANT SELECT on table my_database.myschema.shared_table TO SHARE kumo_share;
Notes:
  1. Only users with the CREATE SHARE privilege can create a secure share. Only the ACCOUNTADMIN has this privilege by default and must be granted to the role creating the secure share for Kumo. See the Snowflake documentation for more details.
  2. Only Secure views can be shared using Snowflake Secure shares.
2. Sharing with Kumo Add KUMO account (select east or west locator based on where your account is located) access to the share. Use the ALTER SHARE command to add one or more accounts access to the share. For example: 
ALTER SHARE KUMO_SHARE_TEST ADD ACCOUNTS=<OrgName>.<Account Name>;
Refer to the region your Snowflake account is in and use the appropriate Kumo account from this table below:
CloudRegionLocatorOrg NameAccount NameEdition
AWSUS West (Oregon)YRB86739LFWGWBPZXA66432Business Critical
AWSUS West (Oregon)YRB86739LFWGWBPKUMOUSWESTEnterprise
AWSUS East (N.Virginia)IUB99615LFWGWBPKUMO_US_EAST1Enterprise
AWSUS East (Ohio)RR45566LFWGWBPKUMO_US_EAST_OHIOEnterprise
AWSUS East (N.Virginia)CZB55260LFWGWBPKUMOUSEAST1BCBusiness Critical
Once the region matches, share the established share with the respective Kumo Snowflake account.

Security Considerations

The following are key security considerations for understanding Kumo’s access mechanism to Snowflake instances.
  1. Database Creation on Kumo’s EndKumo will generate a new database from the share received. It will serve as the central space for EDA and PoV operations.
  2. Defining Access RolesA unique ROLE will be crafted within Kumo’s database to guarantee secured data access.
  3. Allocating Exclusive AccessAccess is provided only to Kumo’s designated Point of Contact, safeguarding your data.

​
Monitoring Access and Activities

  • Queryable Audit Trails: Use SHARE_USAGE, QUERY_HISTORY, and LOGIN_HISTORY views within Snowflake to review Kumo’s interactions.
  • Role-Based Access Control: Monitor the unique ROLE for Kumo to ensure compliant data access.
  • Data Manipulation Monitoring: Use Snowflake’s query history to document any changes made by Kumo.
  • Scheduled Audits: Regularly check logs, role permissions, and shares to guarantee data safety and accuracy.
