As the popularity of GraphQL grows, many hard questions are being asked by companies adopting it as an API standard. What databases or search engines can I use it with? How do you aggregate data from multiple sources globally? Can GraphQL fetched data be available offline, and if clients mutate it how are conflicts resolved?

We’ll learn about AWS AppSync, a managed GraphQL service with offline and realtime features, and see the latest features and functionality that have just been released to market.
