Techniques for delivery guarantee compliance for an application synchronization service are described. In certain embodiments, a publishing service utilizes its memory queue to receive a request to publish a notification of a modification of a monitored data source from an application synchronization service, and then sends a success code to the application synchronization service based at least in part on the storing of the request to publish the notification in the memory queue. Embodiments herein are directed to a publishing service that delivers messages with a level one Quality of Service (QOS) that indicates that a message will be delivered one time at least.

Delivery guarantee compliance for an application synchronization service

A technology is provided for conflict resolution in a data proxy for a mutation. A mutation may be received at a data proxy from an application, and the data proxy is in a service provider environment. The mutation may be sent to be processed by a data store via a data access resolver. A conflict message may be received at the data proxy via the data access resolver for a conflict mutation at the data store for the mutation. The conflict may be resolved at the data proxy using a conflict resolution function in the data proxy.

Conflict resolution in a data proxy

A technology is provided for synchronizing data with delayed subscriptions. A request may be received at a data proxy for a data snapshot for an application that has been offline at the client. A subscription may be held for a pre-determined amount of time after the request for the snapshot. The data snapshot may be sent to the client. The data for the subscription may be sent after the pre-determined amount of time.

Synchronizing data with delayed subscriptions

A technology is provided for mutations with immediate feedback. A mutation may be received at a data proxy from an application. The mutation may be sent to a data source via a data access resolver associated with the data proxy. Results of the mutation may be received from the data source. A subscription may be triggered based on receiving the results of the mutation. A message may be sent via a topic provided by the subscription by using a messaging service such that the messaging service publishes the message with the mutation to devices subscribed to the topic.
