Tag

You can provide configuration to Snowflake Object Lifecycle Engine for the following operations with tag:

• Manage the lifecycle of new and existing tags
• Manage the grants of tags
• Manage masking policies associated with tags

Using this configuration defines the tag as a Snowflake object for further use. It does not apply the tag to an object. For details on how to apply tags to objects within SOLE see SOLE Tags Management.

Usage

note

We have introduced SOLE for Data Products as a new framework for SOLE to help you easily build an ecosystem of data products. The major difference is in how you define Snowflake objects in the configuration file. Rather than having a grouped collection of objects, SOLE for Data Products goes for modular, self-describing, and explicit object definition.
Learn more about SOLE for Data Products, currently available as a private preview.

We have also introduced Data products as an extra layer on top of the Dataops.live platform capabilities making managing data products easier than ever. Learn more about Data Products, currently available as a private preview.

Default Configuration

databases:
  <database-name>:
    schemas:
      <schema-name>:
        tags:
          <tag-name>:
            <configuration-key>: <value>

Data Products Configuration

- tag:
    name: <tag-name>
    <configuration-key>: <value>
    database: rel(database.<database-name>)
    schema: rel(schema.<schema-name>)

Supported parameters

The engine supports the parameters listed below.

Configuration Key	Required/Optional	Data Types and Values	Description
allowed_values	Optional	List of String	List of allowed values for the tag
associated_masking_policies	Optional	Object: See here for a definition of associated_masking_policies	List of masking policy references to apply to the current tag
comment	Optional	String	Specifies a comment for the tag
deleted	Optional	Boolean: True enables deletion prevention, False does nothing	Specifies what objects are allowed to be deleted
grants	Optional	Map: See Supported Tag Grants to Roles	List of Privileges and Roles to which privileges are granted on the current tag
manage_mode	Optional	String: all (default), none, grants	Configures what properties to manage for the tag. See Changing Manage Mode before changing the value.

associated_masking_policies parameter

You can specify one or more masking policies to apply to the tag in the tag definition. Each policy must have a unique data type as combining multiple masking policies with the same data type within a single tag is not allowed. See Masking policy with masking expression in multiple lines for an example of a masking policy with a data type.

List the masking policies under associated_masking_policies in an object format with the following parameters:

Parameter	Required/Optional	Data Type and Values	Description
masking_policy	Required	String	Name of the masking policy
schema	Required	String	Schema of the masking policies identifier
database	Optional	String	Database of the masking policies identifier. If omitted, it defaults to the name of the current database.

Tag applied on Shared objects

If the tag on which the masking policy is set is applied on a shared object, the masking policy will not be unset during the Destroy job to prevent accidental data exposure and might lead to job failure.

To unset the masking policy, you must manually remove it from the tag.

Example

Tag with Single Masking Policy

databases:
  TEST_DATABASE:
    comment: TEST_DATABASE
    schemas:
      TAG_LIBRARY:
        tags:
          CONFIDENTIALITY:
            comment: "CONFIDENTIALITY Tag"
            allowed_values: ["Sensitive", "Highly Sensitive"]
            associated_masking_policies:
              MASK_STRING:
                schema: POLICY_LIBRARY
                database: TEST_DATABASE

Tag with Multiple Masking Policies

databases:
  TEST_DATABASE:
    comment: TEST_DATABASE
    schemas:
      TAG_LIBRARY:
        tags:
          CONFIDENTIALITY:
            comment: "CONFIDENTIALITY Tag"
            allowed_values: ["Sensitive", "Highly Sensitive"]
            associated_masking_policies:
              MASK_STRING:
                schema: POLICY_LIBRARY
                database: TEST_DATABASE
              MASK_POLICY:
                schema: POLICY_LIBRARY
                database: TEST_DATABASE

Supported tag grants to roles

Following is the privilege you can grant to roles in the tag definition:

• APPLY
