We first demonstrate that parallel write operations well perform on a flash storage. P-WAL exploits the features of the flash storage. P-WAL lets each worker writes log records to its dedicated storage space. This design eliminates both the contentions on WAL buffer and the inefficient I/O operations where the conventional sequential WAL method suffers from. We design and implement P-WAL on a prototype transaction manager, and evaluate it with benchmarks. The result of experiments showed that P-WAL outperformed the conventional WAL. The improvement factors were 10.0 on micro-benchmark and 2.3 on TPC-C benchmark respectively.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"39","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"24","bibliographicIssueDates":{"bibliographicIssueDate":"2017-03-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"10"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:47:56.156940+00:00","id":178598,"links":{}}
