Abstract: A method and system for processing work items. Information identifying work items from a server responsible for handling work items based on a set of configuration rules is retrieved and stored in a cache that includes N containers. Responsive to a work item request from an application, searching is performed for matching work items in the cache. The work item request specifies n+1 criteria for work items such that n+1 is at least 2, wherein N is a product over a cardinality Ci of criterion i from i=0 through i=n, wherein C0=1 and Ci?2 for i=1 through i=n. Responsive to finding work item(s) matching the work item request, a piece of information is identified to the application the matching work item(s) from the cache. Information identifying work items of an allowable type of work item is stored in a respective container.

Abstract: A method for processing work items of a workflow system is done in the following manner. Information identifying work items from a server responsible for handling work items is retrieved based at least on a set of configuration rules. The information is stored in a cache. In response to a work item request form an application, matching work items are searched for in the cache, and a piece of information identifying the requested work item is delivered to the application in response to finding at least one work item matching the work item request from the application. Statistics on work item requests are maintained, and the set of configuration rules are modified according to the statistics.
