Summary: Improve Process Group Status Authorization Handling
Key: NIFI-13476
URL: https://issues.apache.org/jira/browse/NIFI-13476
Project: Apache NiFi
Issue Type: Improvement
Reporter: David Handermann
Assignee: David Handermann
The NiFi user interfaces calls the REST API on a recurring basis to retrieve
Process Group status information for presentation on the canvas. Part of the
status retrieval process involves recursive component evaluation to present
aggregate metrics and summary information. The Process Group status retrieval
method involves a parameter to limit the recursion depth, but that limit does
not apply to authorization checking for individual components, resulting in
many unnecessary authorization checks, based on the number of nested
components. The status retrieval method can be optimized to avoid calling the
Authorizer when the nested components will not be included in the Process Group
status.
