>
> 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.
