| Abstract(in English) | We proposed a new concurrency control method, MARK-OPT, for parallel Btree structures, such as the Fat-Btrees. Previous experimental results demonstrated that the MARK-OPT was effective in the environment where the access frequencies were uniform. In this paper, we evaluate the influence of access skews on the MARK-OPT to show that the method is also effective even when the access pattern has skew. To mitigate the access skew, data should be migrated between data storages. We then evaluate the performance of the MARK-OPT with the data migration. Experiments with changing the pattern of the data migration indicate that the MARK-OPT is also effective as a concurrency control method for data migration. |
