The B-link can achieve excellent concurrency control, which uses links to chain all nodes at each level together. In the B-link algorithm, neither readers nor updaters latch-couple on their way down to a leaf node and they acquire the latch only on one node at a time. However, it is difficult to guarantee the consistency of the side pointers if the B-link is applied to whole of a parallel Btree structure. In this paper, a new concurrency control method using the B-link on the Fat-Btree, a parallel Btree structure, to reduce the frequency of X latches and the range of X latches at a time. To compare the performance of the proposed method and the conventional method, we implemented them on an autonomous-disk system adopting the Fat-Btree. The experimental results with changing update ratio indicate that the proposed method always improves the system throughput, and are especially effective for higher update ratio configuration. |
