Description RHOS Integration 2014-12-04 00:12:42 EST

Cloned from launchpad blueprint https://blueprints.launchpad.net/glance/+spec/store-capabilities.

Description:

Storage capabilities is used to indicate the static and dynamic ability
of the storage driver instance based on current driver implementation and
particular driver configuration and backend storage status at runtime.

Use storage capabilities, glance_store can do more proper operations on
storage to support upper layer request, like to enable or disable image
adding function to glance, or if allow glance reuse driver instance for all
request according to whether the driver and/or the operation session of
backend storage is stateless.
