Support multiple unique fields in dgraph GraphQL

[sessionboy]

What you wanted to do

Expect team to provide support for multiple unique fields in dgraph GraphQL, this is a very common requirement, like this:

 type User {
    id: ID!
    name: String! @unique
    username: String! @unique
    phone_number: String! @unique
    email: String @unique
    ...
 }

The unique field is allowed to be empty, and no verification is performed when the value of the unique field is empty. For example email above.

Any external references to support your case

prisma provides a great implementation for this, which can be used as a reference.

Hi, thanks for the suggestion.

We'll take this onboard as we look at GraphQL features. No commitment yet on what we'll support, but it would be great to support composite keys as well as the kind of uniqueness described here.

Thanks for team efforts, I look forward to it.
