Description
|
|
===========
|
|
|
|
:program:`nova-api-metadata` is a server daemon that serves the Nova Metadata
|
|
API. This daemon routes database requests via the ``nova-conductor`` service,
|
|
so there are some considerations about using this in a
|
|
:ref:`multi-cell layout <cells-v2-layout-metadata-api>`.
