Predictability is an important virtue that has long been neglected by the database research community. However, with the performance of modern database systems becoming more and more unpredictable, the task of provisioning and tuning databases has become more and more difficult.
In this project, we aim to bring back such an important aspect of database systems by redesigning certain components of the database systems, so that the database systems not only provides high performance, but also maintains such high level of performance.
