-----------------------------------------
Summary: Enable caching in DatabaseUserGroupProvider and
DatabaseAccessPolicyProvider to improve performance
Key: NIFI-14245
URL: https://issues.apache.org/jira/browse/NIFI-14245
Project: Apache NiFi
Issue Type: Improvement
Components: NiFi Registry
Reporter: Yoshiaki Takahashi
Assignee: Yoshiaki Takahashi
When DatabaseUserGroupProvider and DatabaseAccessPolicyProvider are applied in
NiFi Registry, the Web UI's user list display slows down as the number of users
increases.
This is because the current implementation runs more SQL queries in proportion
to the number of users.
By adding a cache mechanism to eliminate unnecessary SQL executions, we can
speed up the user list display.
