AWS AppSync is an app data management service that helps companies to develop GraphQL APIs through which they can securely connect to data sources like Lambda AWS DynamoDB and more.
GraphQL is a data language that developers use in their apps to change, fetch and subscribe to data from the servers, accordingly. AWS AppSync lets users specify which part of the data must be available to access by the app in a real-time manner with the help of GraphQL Subscriptions. The service comes with an Amplify DataStore featuring a local-first programming model where apps can interact with data seamlessly, in both online and offline modes. With AWS AppSync, developers can give their applications the ability to determine data requirements with the help of GraphQL so that only the required data is accessed. Finally, the server-side data caching capabilities of the AWS AppSync reduce the need to directly access data sources by offering the data in high-speed in-memory managed caches.
