Although flash storage has many distinguished\n   hardware features, it still suffers from the poor I\/O performance in the\n   case of update operations. Due to the absence of in-place updates,\n   differently from HDDs, flash storage needs to modify data through\n   out-of-place updates. For this reason, it is required to continuously renew\n   the mapping information between a logical page address and its new physical\n   address, invalidating its old physical address. When the invalidated pages\n   swallow most of free space in flash storage, the actions of garbage\n   reclamation are needed. Since the actions of garbage reclamation are very\n   costly, it is crucial to reduce the number of update operations for the use\n   of flash storage in enterprise-scale database systems. In this light, we\n   propose a new buffering scheme that evicts dirty pages without writing them\n   to storage, thereby reducing the amount of update operations considerably.\n   That is, our buffering scheme enables the flushing-less evictions of dirty\n   pages. To correctly read a page undergoing its flushing-less eviction, we\n   propose a new on-the-fly redo mechanism that enables restoring the lost\n   updates of the page in normal database processing. For fast execution of the\n   on-the-fly redo, we maintain memory-resident log data of a reasonable size.\n   To show the performance advantages of the proposed scheme, we performed\n   extensive experiments based on the TPC-C benchmark, by running them on the\n   open-sourced Berkeley DB equipped with\/without our scheme. The results show\n   that our scheme yields a much better performance by reducing the amount of\n   page updates significantly.<\/jats:p>","DOI":"10.2298\/csis160830014j","type":"journal-article","created":{"date-parts":[[2017,7,5]],"date-time":"2017-07-05T14:48:49Z","timestamp":1499266129000},"page":"369-392","source":"Crossref","is-referenced-by-count":0,"title":["A flash-aware buffering scheme with the on-the-fly redo for efficient data management in flash storage"],"prefix":"10.2298","volume":"14","author":[{"given":"Kyosung","family":"Jeong","sequence":"first","affiliation":[{"name":"Hanyang University, Dept. of Computer and Software, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sungchae","family":"Lim","sequence":"additional","affiliation":[{"name":"Dongduk Women\u2019s University, Dept. of Computer Science, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kichun","family":"Lee","sequence":"additional","affiliation":[{"name":"Hanyang University, Dept. of Industrial Engineering, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang-Wook","family":"Kim","sequence":"additional","affiliation":[{"name":"Hanyang University, Dept. of Computer and Software, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1078","container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:33:22Z","timestamp":1685349202000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02141702369J"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2017]]}},"URL":"https:\/\/doi.org\/10.2298\/csis160830014j","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
