ABAC_POLICY_DEFINITIONS
Applies to: 
Databricks SQL Databricks Runtime Unity Catalog only
This feature is in Public Preview.
INFORMATION_SCHEMA.ABAC_POLICY_DEFINITIONS returns one row per attribute-based access control (ABAC) policy attached to a securable object in the local catalog. Each row contains the policy definition, including its scope, policy type, target conditions, applicable principals, and the condition used to enforce the policy. This view returns the same policy details as DESCRIBE POLICY for every policy in the catalog.
You can see only policies for which you have MANAGE on the catalog, schema, or table where the policy is attached. This matches the access pattern of DESCRIBE POLICY.
This relation is an extension of the SQL Standard Information Schema.
