Method and system for delivering object update messages including payloads

摘要

A distributed network system includes at least one server and one client device, each having memory and one or more processors. The server performs the following operations: selecting a first client-object registration record including a first client identifier and a first object identifier; retrieving a pair of server-side object version and client-side object version from the first client-object registration record; determining a first set of incremental payloads to be delivered to the client device associated with the first client identifier in accordance with the pair of server-side object version and client-side object version; retrieving the first set of incremental payloads from a first object update record including the first object identifier; and sending a first object update message to the first client device, wherein the first object update message includes the first object identifier, the server-side object version and the retrieved first set of incremental payloads.
