| Abstract(in English) | Skew handling is one of the most important techniques for the performance and scalability of parallel database systems. The evaluation of load in each disk is a crucial factor to the skew handling. We propose a directory-traverse-cost based load-evaluation algorithm considering accesses for intermediate nodes in the distributed directory. We also porpose an O(|Disk#|)parallel skew handling algorithm using the proposed load-evaluation algorithm. We compare the convergence process and effectiveness of our load-evaluation algorithm with ordinary ones. |
