I tried to follow example of Apollo Federation with “Composition in Apollo studio part”
And I did running command
rover subgraph publish for Register subgraph schemas.
But i met below message
The graph My-Graph-3-fthtu@current
is a non-federated graph. This operation is only possible for federated graphs.
I tried to find creating federated graphs at “New Graph” popup in Apollo Studio, but there wasn’t anywhere.
So, What is the federated graph and How to make it in Apollo studio?
I really want to continue this tutorial. please help…
