[Feature Request] Ordered and Any_of should also work for only partial settings

[manzke]

Right now we have to duplicate all keys to make it working with any_of or ordered.

Example:

ordered: 
    - region: eu-central-1
      accelerators: A10G:1
      memory: 24+
    - region: eu-central-1
      accelerators: T4:4
      memory: 24+
    - region: eu-west-1
      accelerators: A10G:1
      memory: 24+
    - region: eu-west-2
      accelerators: A10G:1
      memory: 24+
    - region: eu-west-3
      accelerators: A10G:1
      memory: 24+
    - region: eu-north-1
      accelerators: A10G:1
      memory: 24+
    - region: eu-west-1
      accelerators: T4:4
      memory: 24+
    - region: eu-west-2
      accelerators: T4:4
      memory: 24+
    - region: eu-west-3
      accelerators: T4:4
      memory: 24+
    - region: eu-north-1
      accelerators: T4:4
      memory: 24+

What would be amazing if this would work too:

accelerators: [A10G:1, T4:4]
memory: 24+
ordered: 
    - region: eu-central-1
    - region: eu-west-1
    - region: eu-west-2
    - region: eu-west-3
    - region: eu-north-1

Cc @MaoZiming. It seems like it's unambiguous to support

• ordered x unordered
• undered x unordered

while we cannot support ordered x ordered in general.

Hi, @manzke thanks for the question! Currently we do not support ordering along multiple fields (e.g. accelerators and regions), as it is unclear how to compare ordering across fields. For example, ordering A10G:1 and eu-north-1 with T4:4 and eu-central-1, where A10G:1 is ordered before T4:4 but eu-north-1 is ordered after eu-central-1. We are still figuring out the interface. Let us know if you have any suggestions!
