Abstract

Previous page storage models do not show good performance in mixed OLAP and OLTP workloads because they are originally designed for only one of these workload types. Therefore, we propose a new page storage model for mixed OLAP and OLTP workloads which is based on column groups. We also present a dynamic page layout method that generates correlated column groups by analyzing the current workload and then dynamically reorganizes the data pages. The proposed page model shows a considerable performance improvement in the mixed workload environment.
