// Amazon Cognito Sync provides an AWS service and client library that enable
// cross-device syncing of application-related user data. High-level client
// libraries are available for both iOS and Android. You can use these libraries
// to persist data locally so that it's available even if the device is offline.
// Developer credentials don't need to be stored on the mobile device to access
// the service. You can use Amazon Cognito to obtain a normalized user ID and
// credentials. User data is persisted in a dataset that can store up to 1 MB
// of key-value pairs, and you can have up to 20 datasets per user identity.
//
// With Amazon Cognito Sync, the data stored for each identity is accessible
// only to credentials assigned to that identity. In order to use the Cognito
// Sync service, you need to make API calls using credentials retrieved with
// Amazon Cognito Identity service (http://docs.aws.amazon.com/cognitoidentity/latest/APIReference/Welcome.html).
//
// If you want to use Cognito Sync in an Android or iOS application, you will
// probably want to make API calls via the AWS Mobile SDK. To learn more, see
// the Developer Guide for Android (http://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/cognito-sync.html)
// and the Developer Guide for iOS (http://docs.aws.amazon.com/mobile/sdkforios/developerguide/cognito-sync.html).
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
