Versioned schemas: Disallow tag propagation¶

The behavior of versioned schemas and tags in a Snowflake Native App is as follows:

Before the change:

Tag propagation in a Snowflake Native App occurs with a versioned schema under the following conditions:

• Create a tag in the versioned schema and assign the tag to an object in a different schema.

• Create a tag in a non-versioned schema and assign the tag to an object in a versioned schema.

• Create tables or views in the versioned schema and assign a tag to the tables or views when the tag exists in a non-versioned schema.

• Create tables or views in a non-versioned schema and assign a tag to the tables or views when the tag exists in a versioned schema.

In these cases, tag propagation refers to tags being set on objects when the versioned schema increments to the next version.

After the change:

Tag propagation does not occur with versioned schemas in a Snowflake Native App and results in the following error message:

A TAG in a versioned schema can only be assigned to the objects in the same schema. An object in a versioned schema can only have a TAG assigned that is defined in the same schema.

To prevent the error message, the Snowflake Native App provider should update the setup script to ensure that tags are set on objects within the same schema as the tag when a versioned schema contains either the tag or the object on which the tag is set. If a non-versioned schema contains either the tag or the object on which the tag is set, it is not necessary to update the setup script.

If you are a consumer of the Snowflake Native App and you see this error message after installing the app, ask the provider to update their set up script.
