An application server of a server cluster may store a payload of a write request in a local cache and thereafter serve read requests based on payloads in the local cache if the corresponding data is present when such read requests are received. The payloads are however later propagated to respective data stores at a later suitable time. Each application server in the server cluster retrieves data from the data stores if the required payload is unavailable in the respective local cache. According to another aspect, an application server signals to other application servers of the server cluster if a required payload is unavailable in the local cache. In response, the application server having the specified payload (in local cache) propagates the payload with a higher priority to the corresponding data store, such that the payload is available to the requesting application server.
