User Permissions and Roles
User Privileges
Privileges consist of two components: an action and an object. An action refers to a type of operation that is permitted to be carried out on an object:
List of Actions
Some privileges must specify the exact object with which the relation applies to by using a selector. In this case the object is a specific entity, identified by its name, such as a schema, table, view, configuration, deployment unit and others. For example, CLUSTER_CONFIG - READ_CLUSTER_CONFIG does not have a selector. ALTER_SCHEMA - SCHEMA needs to specify which schema should be used (PUBLIC, MY_SCHEMA_NAME). These privileges are listed below as Has selector.

Object Permission Hierarchy
Objects in GridGain 9 are organized in hierarchy:
Actions allowed on the object are also allowed on its children. For example, if you have a PUBLIC schema and allow the SELECT_FROM_TABLE action on it, the user with the role will be able to perform the SELECT SQL action on all tables in the PUBLIC schema.
