Is there any way to generate a union schema during build time so that we can use the static schema to compose supergraph?

[icypig]

As I know dgs supplied a query named _service so that we can use rover introspect way to publish the subgraph schema, I'm wondering if there is any way that dgs can generate a union graphql schema so that we can use rover with static schema file to compose supergraph?

Thanks a lot~

What do you mean by a union graphql schema? You mean for the whole composed graph that the DGS is a part of? That would be provided by the federated gateway. The DGS has no knowledge of the entire graph by itself.
