Methods and system for maintaining data coherency in distributed data cache network

Techniques for distributed cache management are provided. A server having backend resource includes a global cache and a global cache agent. Individual clients each have client cache agents and client caches. When data items associated with the backend resources are added, modified, or deleted in the client caches, the client cache agents report the changes to the global cache agent. The global cache agent records the changes and notifies the other client cache agents to update a status of the changes within their client caches. When the changes are committed to the backend resource each of the statuses in each of the caches are updated accordingly.
