100% agree. I'm utterly confused why it's not in the library.

I'm using apoc.schema.assert right after the connection has been verified (driver.verifyConnectivity()).
e.g.: CALL apoc.schema.assert(null,{Product:['id']}) to prevent duplicate product IDs.
This works quiete well and gets executed every time I redeploy/restart the ApolloServer.

Would @Unique work in a similar way? Does this approach conflict with your internal index management or future @Unique implementation?
