IMPLEMENTING SYNCHRONIZATION OF STATE INFORMATION BETWEEEN INSTANCES OF AN APPLICATION AS WELL AS BETWEEN DIFFERENT APPLICATIONS IN AN EFFICIENT, SCALABLE MANNER

摘要

A method, system and computer program product for implementing synchronization of state information in an efficient, scalable manner. A shared state server receives a request from a client device to access a scope containing state information. The scope is distributed over a partition(s) via the use of a “data grid” thereby increasing scalability. The shared state server relays the request to a data grid server responsible for maintaining the data grid comprised of an in-memory cache and partitions outside of the in-memory cache. The request includes a key associated with a value corresponding to the requested state information. The data grid server obtains the value associated with the key from its data grid and sends it to the shared state server to be relayed to the requesting client device. In this manner, the state information is stored in a scalable manner thereby improving the efficiency in synchronizing state information.

1. A computer program product embodied in a computer readable storage medium for implementing synchronization of state information in an efficient, scalable manner the computer program product comprising the programming instructions for:
receiving a request relayed from a first server, wherein said request is a request from a first client device to obtain state information stored in a scope, wherein said scope is distributed over one or more partitions, wherein said request comprises a key associated with a value corresponding to said state information; identifying one of said one or more partitions storing said value associated with said key; obtaining said value from said one of said one or more partitions; and sending said value to said first server to be relayed to said first client device.
