Today's internet services need to handle extensive traffic loads because users not only read the information but also become information contributors, producing massive writings. To cope with the situation, service providers usually involve multi-layered caching backup mechanisms to facilitate data access and upgrade system scalability.

For internet servers, how to handle the huge amounts of messages has become a major challenge.
