| Abstract(in English) | We propose a data migration amount computation formula for parallel skew handling method targeting fast skew removal. This suppresses the transient skew increasement during parallel access skew handling. For scalable parallel data storing systems, it is important that the system has an online data declustering mechanism which balances skewed access requests. Access skews generated by changing access pattern should be resolved in short time. The effect of skew handling is affected by the amount of data being migrated by one execution. The goals of our proposal are fast removal of large skews and decreasing insufficient migration caused by error in load evaluation. |
