Abstract

Embodiments of the present invention address deficiencies of the art in respect to data synchronization and provide a method, system and computer program product for protocol optimization for client and server synchronization. In one embodiment a protocol optimization method for client and server synchronization can be provided. The method can include receiving server updates from a synchronization server, and applying each update to a client data store in parallel to requesting additional ones of the server updates from the synchronization server before completing the application to the client data store. In one aspect of the embodiment, receiving server updates from a synchronization server can include receiving server update subsets of a singular server update for a synchronization conversation from a synchronization server.

Claims

1. An optimized synchronization protocol enabled data processing system comprising:

a synchronization client configured for communicative coupling to a synchronization server for a common application over a communications medium;

a data store of data for the common application; and

,

a data store agent coupled to each of the synchronization client and the data store, the agent comprising program code enabled to process updates to the data store for the common application on behalf of the synchronization client in parallel with the synchronization client exchanging communications with the synchronization server as part of a synchronization conversation.

2. The system of claim 1, wherein the communications medium is a wireless data network.

3. The system of claim 1, wherein the communications medium is a wirebound data network.

4. The system of claim 1, wherein the updates are subsets of a single server update for the synchronization conversation.

5. The system of claim 4, wherein the agent further comprises additional program code enabled to assign pre-allocated temporary local identifiers to local objects associated with the subsets and to provide the assigned pre-allocated temporary local identifiers to the synchronization server responsive to receiving the subsets from the synchronization server.

6. A protocol optimization method for client and server synchronization, the method comprising:

receiving a plurality of server updates from a synchronization server; and

,

applying each update to a client data store in parallel to requesting additional ones of the server updates from the synchronization server before completing the application to the client data store.

7. The method of claim 6, wherein receiving a plurality of server updates from a synchronization server, comprises receiving a plurality of server update subsets of a singular server update for a synchronization conversation from a synchronization server.

8. The method of claim 7, further comprising notifying the synchronization server when all of the server update subsets of the singular server update have been received and applied to the client data store.

9. The method of claim 6, wherein applying each update to a client data store in parallel to requesting additional ones of the server updates from the synchronization server before completing the application to the client data store, comprises applying each update to a client data store in a parallel executing thread of execution while requesting additional ones of the server updates from the synchronization server in a separate parallel executing thread of execution before completing the application to the client data store.

10. The method of claim 8, further comprising:

pre-allocating temporary local identifiers for assignment to local objects associated with incoming ones of the server update subsets;

providing a mapping of the pre-allocated temporary local identifiers corresponding to the local objects to the synchronization server; and

,

providing an updated mapping to the synchronization server when all of the server update subsets of the singular server update have been received and applied to the client data store.

11. The method of claim 8, further comprising:

detecting an interruption in the synchronization conversation; and

,

resuming the synchronization conversation at a point proximate to a last processed server update subset.

12. A computer program product comprising a computer usable medium having computer usable program code for protocol optimization for client and server synchronization, the computer program product including:

computer usable program code for receiving a plurality of server updates from a synchronization server; and

,

computer usable program code for applying each update to a client data store in parallel to requesting additional ones of the server updates from the synchronization server before completing the application to the client data store.

13. The computer program product of claim 12, wherein the computer usable program code for receiving a plurality of server updates from a synchronization server, comprises computer usable program code for receiving a plurality of server update subsets of a singular server update for a synchronization conversation from a synchronization server.

14. The computer program product of claim 13, further comprising computer usable program code for notifying the synchronization server when all of the server update subsets of the singular server update have been received and applied to the client data store.

15. The computer program product of claim 12, wherein the computer usable program code for applying each update to a client data store in parallel to requesting additional ones of the server updates from the synchronization server before completing the application to the client data store, comprises computer usable program code for applying each update to a client data store in a parallel executing thread of execution while requesting additional ones of the server updates from the synchronization server in a separate parallel executing thread of execution before completing the application to the client data store.

16. The computer program product of claim 14, further comprising:

computer usable program code for pre-allocating temporary local identifiers for assignment to local objects associated with incoming ones of the server update subsets;

computer usable program code for providing a mapping of the pre-allocated temporary local identifiers corresponding to the local objects to the synchronization server; and

,

computer usable program code for providing an updated mapping to the synchronization server when all of the server update subsets of the singular server update have been received and applied to the client data store.

17. The computer program product of claim 14, further comprising:

computer usable program code for detecting an interruption in the synchronization conversation; and

,

computer usable program code for resuming the synchronization conversation at a point proximate to a last processed server update subset.
