Disclosed are various embodiments for synchronizing application state information across devices. More specifically, embodiments of the disclosure are related to resolving conflicts between application state information. A synchronization rule, an event name and/or event value are embedded within application state information obtained from devices associated with a user, from which conflicts can be resolved by an application synchronization service.

Resolving conflicts within saved state data

Disclosed are various embodiments for synchronizing application state information across devices. More specifically, embodiments of the disclosure are related to facilitating idempotency of application state information. Idempotency is maintained by using a timestamp embedded within application state information and/or by determining that the application state information is associated with an accumulating value.

Idempotency of application state data

A subscription management service utilizes a timer service to maintain timers corresponding to subscription events. The subscription management service exposes an interface through which clients can define new subscriptions that are then created and managed by the subscription management service. The subscription management service can charge subscribers on an appropriate billing period, and cancel or automatically renew subscriptions at the end of a contract period. The subscription management service can also provide notifications to clients, to subscribers, and/or to other components. The subscription management service might also perform other types of actions with regard to the subscriptions on behalf of the clients. The timer service receives payloads from clients, such as the subscription management service, and provides the payloads back to the clients at a specified time. The timer service might also utilize a jitter threshold to compute the time at which payloads should be provided to clients.

Disclosed are various embodiments for synchronizing application state information across devices. More specifically, embodiments of the disclosure are related to generating and storing of application state information. Key-value pairs are stored on a client device and synchronized with an application synchronization service.
