4 This release provides an EXPERIMENTAL implementation of the Glance spec
5 `Multi-Store Backend Support
6 <https://specs.openstack.org/openstack/glance-specs/specs/rocky/implemented/glance/multi-store.html>`_,
7 which allows an operator to configure multiple backing stores so that
8 end users may direct image data to be stored in a specific backend.
9 See `Multi Store Support
10 <https://docs.openstack.org/glance/latest/admin/multistores.html>`_
11 in the Glance Administration Guide for more information.

13 This experimental feature is optionally exposed as the EXPERIMENTAL
14 Image Service API version 2.8. Its use in production systems is currently
15 **not supported**. We encourage people to use this feature for testing
16 purposes and report any issues so that it can be made stable and fully
17 supported in the Stein release.

20 The `Multi-Store Backend Support
21 <https://specs.openstack.org/openstack/glance-specs/specs/rocky/implemented/glance/multi-store.html>`_
22 feature is introduced on an experimental basis in the EXPERIMENTAL
23 Image Service API version 2.8:
24
25 * a new *list stores* call, `GET /v2/info/stores
26 <https://developer.openstack.org/api-ref/image/v2/index.html#list-stores>`_
27 * a new ``OpenStack-image-store-ids`` header in the `create image
28 <https://developer.openstack.org/api-ref/image/v2/index.html#create-image>`_
29 response
30 * an ``X-Image-Meta-Store`` header may be included with the `image data
31 upload
32 <https://developer.openstack.org/api-ref/image/v2/index.html#upload-binary-image-data>`_
33 request
34 * an ``X-Image-Meta-Store`` header may be included with the `image import
35 <https://developer.openstack.org/api-ref/image/v2/index.html#import-an-image>`_
36 request
37
38 Please keep in mind that as version 2.8 of the Image Service API is
39 EXPERIMENTAL, we reserve the right to make modifications to these aspects
40 of the API should user feedback indicate that a change is required.
