[Starlingx-discuss] What's the use case of these 2 patches?

[Rowsell, Brent]

Liang,

This was a small usability improvement to help the user distinguish the glance backend type in a multi backend environment.

Compare with upstream glance, starlingx added "Store" column as below
+-----+--------+-------+-----------------+-----+------------+--------+---------+
| ID   | Name | Store | Disk_format | ...    | Size           | Status |Owner|
+-----+--------+-------+-----------------+-----+------------+--------+---------+
| xxx | img1   | file     | raw                    | ...   | 10737418 | active | xxx      |
| xxx | img2   | file     | raw                    | ...   | 5086345   | active | xxx      |
+-----+--------+-------+-----------------+-----+------------+--------+---------+

Hi

I'm working on upstreaming below 2 patches and the code review was slightly blocked because community need to know the use case:
Commit from glanceclient: 75967f4c9c9ca582277d036581effcac0c7ee5a9: Show glance_backend rbd or file.
Commit from glance: f6ad3a44303a1bf9abec91e1d679cdd13fb9c4f6: Add store info in glance image-list and image-show

Could anybody share the original intention of these two patches? What's the use case of saving/showing the store info? It seems end user cannot do anything with this information. Thanks!

Regards
Liang
