=== Operator-only functionality

NOTE: {cloud-only}

Operator privileges provide protection for APIs and dynamic cluster settings.
Any API or cluster setting that is protected by operator privileges is known as
_operator-only functionality_. When the operator privileges feature is enabled,
operator-only APIs can be executed only by operator users. Likewise,
operator-only settings can be updated only by operator users. The list of
operator-only APIs and dynamic cluster settings are pre-determined in the
codebase. The list may evolve in future releases but it is otherwise fixed in a
given {es} version.
