| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, storage disaggregation architecture has been attracting attention because it enables cost optimization by separating compute nodes from storage nodes and scaling each of them independently. On the other hand, LSM-tree, which is widely used in modern KVS, is known to worsen the performance of write-intensive workloads due to the compaction bottleneck. If the LSM-tree is simply implemented in a storage disaggregation architecture, the compaction process is performed on the compute nodes, which increases communication and reduces the compaction processing speed, thus affecting the overall performance. Therefore, we propose a method to improve the performance by offloading the compaction process to the storage node and reducing the amount of communication. As a result, the throughput is improved by up to 75% in the emulation evaluation. | |
