Hi Ed Leafe,
Thanks your reply.
Open API defines a standard interface description for REST APIs.
Open API 3.0 can make a description(schema) for current OpenStack REST
API.
It will not change current OpenStack API.
I am not a GraphQL expert. I look up something about GraphQL.
In my understanding, GraphQL will get current OpenAPI together and
provide another APIs based on Relay,
Not sure what you mean here, could you please develop?
and Open API is used to describe REST APIs and GraphQL is used to
describe Relay APIs.
There is no such thing as "Relay APIs".
GraphQL povides a de-facto API Schema and Relay provides extensions on
top to facilitate re-fetching, paging and more.
GraphQL and OpenAPI have a different feature scope and both have pros
and cons.
GraphQL is delivering API without using REST verbs as all requests are
undone using POST and its data.
Beyond that what would be great (and it will ultimately come) is to have
both of them working together.
The idea of the GraphQL Proof of Concept is see what it can bring and at
what cost such as effort and trade-offs.
And to compare this against the effort to adapt OpenStack APIs to use
Open API.
BTW what's the status of Open API 3.0 in regards of Microversion?

Gilles

There is currently an effort by some developers to investigate the
possibility of using GraphQL with OpenStack APIs. What would Open
API 3.0 provide that GraphQL would not? I’m asking because I don’t
know enough about Open API to compare them.
