Among the increasing number of online businesses, a series of write-intensive commercial workloads are emerging recently on the Internet. These workloads generate many more write transactions on the backend database than read transactions. Most of such workloads require the database to handle high-volume write transactions in real-time. Based on the observation on the workloads, this paper proposes a multi-tier database scale-out architecture with the write caching technology. Our preliminary result shows that the database scale-out architecture can handle extremely high-volume write transactions with excellent scalability.
