------------------------------------
Summary: Static Attribute Ingestion
Key: SENTRY-2189
URL: https://issues.apache.org/jira/browse/SENTRY-2189
Project: Sentry
Issue Type: Bug
Reporter: Liam Sargent
Assignee: Liam Sargent
Static (file-based) attribute provider for Sentry ABAC.
Attributes are string "tags" used to define a feature of the data which may
require additional access control steps for security and compliance.
Since Sentry already provides role-based access control, we must be able to
define actions to take on data objects based on attribute/role combinations.
For instance, a column marked with the attribute "Sensitive Data" may be
visible to someone with "ROLE_ADMIN", but needs to be NULLed for someone with
the the role "SALES", etc. This relationship can be modeled and effectively
leveraged at query time with a specialized Bidirectional map object providing
low latency lookup between Attribute/Role and Object/Action, and vice versa.
Attribute/Role->Object/Action definitions will be provided as a JSON object, or
as JSON delta updates to existing definitions. This implementation will parse
the definitions into the specialized Java object to provide near-O(1) lookup
from Attribute/Role -> Object/Action, and from Object -> Attribute/Role
associations.
