database engine, which is one of the major architectures of the database engine, has been widely used. Shared-storage database engine achives high availability against a fault in the computing resources by sharing a storage among computing resources. With shared-storage database engine, for a query where the throughput is limited by the computing resources, a query throughput can be controlled by specifying the amount of computing resources. However, in a conventional shared-storage database engine, the amount of computing resources is determined at the beginning of query execution, thus the opportunity of specifying the amount of computing resources used for query execution is limited before the execution of the query. In this paper, we propose a method to adjust the amount of computing resources to be utilized for query execution during query execution. The proposed method improves the efficiency of computing resource utilization in shared-storage database engine. For example, the proposed method allows the shared-storage database engine to allocate the available resources to the currently executing query even if the resources were not available before the execution of the query. We present experimental evaluations using the public cloud environment and clarify the effectiveness of the proposed method.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"43","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"30","bibliographicIssueDates":{"bibliographicIssueDate":"2018-07-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"11"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":190378,"links":{}}
