You did it!

Fantastic job completing this server-side lab. You've tackled from start to finish the task of bringing in a new feature to our API. From to datafetchers, the Artist type is now part of our music catalog app.

But what better way to end a solo mission than with another challenge? Check out the implementation of the Track.artist datafetcher, and see if you notice something in need of a performance tune-up...

Then, check out the next course in the DGS series: Data Loaders with Java & DGS. The journey continues!
