Video Info: As an organization’s data graph grows, Jeff Hampton, Solutions Architect at Apollo, explains how to use Apollo Federation to improve efficiency and scale GraphQL.
Apollo Federation is a new architecture for GraphQL, where you can now divide the implementation of a data graph across distinct, composable services. With this approach, different teams can collaborate across a single graph whose implementation is loosely-coupled.
Jeff will cover the architectural principles behind federation and show how you can implement a well designed and structured data graph using Apollo.

[NewBie] [time - 20:50] It seems odd that I am querying for reviews by me and if I want each review to also include 'name' then another call to account service is required. Can the federation itself correlate that it already received 'name' from accounts service and can now populate it for each review instead of making a network call ?

Thanks for the question! Yes, check out our video on how to use the @key directive to avoid making another call czcams.com/video/6Bj2ByOBRa4/video.html
