InfiniDB (formerly Calpont Corporation〔http://infinidb.co/about/news/calpont-announces-company-name-change-infinidb-and-secures-new-funding〕) used to be a database management software company based in Frisco, Texas. The company develops InfiniDB, a scalable, software-only columnar database management system〔http://www.cmswire.com/cms/enterprise-cms/infinidb-20-supports-big-data-analytics-009089.php〕 for analytic applications.〔http://www.enterpriseirregulars.com/28857/calpont%E2%80%99s-infinidb-%E2%80%93-another-adbms-insurgent-arises/〕 InfiniDB was selected as finalist in the Best Database Solution category at the 26th and 27th SIIA Annual CODiE Awards.〔http://www.siia.net/codies/2011/finalist_detail.asp?id=9〕〔http://www.prweb.com/releases/2012/3/prweb9313454.htm〕 InfiniDB is a scalable database built for big data analytics, business intelligence, data warehousing and other read-intensive applications.〔 InfiniDB's column-store architecture enables very quick load and query times.〔http://www.mysqlperformanceblog.com/2010/01/07/star-schema-bechmark-infobright-infinidb-and-luciddb/〕 Its massive parallel processing (MPP) technology scales with any type of storage hardware.〔http://www.infinidb.org/blogs/view/81-infinidb-to-1-trillion-rows-1039909436172-〕 == Columnar Databases == By storing and managing data based on columns rather than rows, column-oriented architecture overcomes query limitations that exist in traditional row-based RDBMS. Only the necessary columns in a query are accessed, reducing I/O activities by circumventing unneeded rows.〔http://www.youtube.com/watch?v=UTKcAdrjt1Y〕 InfiniDB is accessed through a MySQL interface.〔http://www.information-management.com/gallery/-10021367-1.html?start=21〕 It then parallelizes queries and executes in a Map-Reduce fashion (similar in concept to the methodology used by Apache Hadoop).〔http://tm.durusau.net/?cat=666〕 Each thread within the distributed architecture operates independently, avoiding thread-to-thread or node-to-node communication that can cripple scaling.〔http://infinidb.org/blogs/view/93-a-behind-the-scenes-look-at-infinidb-part-2-of-3〕 InfiniDB is used to enable performance-intensive analytic applications. Customers include Bandwidth.com, Tucows, Warner Music Group,〔http://www.calpont.com/warner-music-group-case-study-video〕 Genus,〔http://strataconf.com/strata2012/public/schedule/speaker/129424〕 Aviation Software International,〔http://www.aviation-software.net/news/news-asi-calpont.html〕 Caring Bridge,〔http://www.information-management.com/issues/21_3/calpont-infinidb-10020717-1.html〕 Navigant Consulting and 1&1 Internet.〔http://www.calpont.com/customers〕 InfiniDB resellers include SkySQL (including many former MySQL employees)〔http://www.business-intelligence.net/blog/calpont-infinidb-becomes-strategic-component-of-the-skysql-reference-architecture〕 and KK Ashisuto in Japan.〔http://digitaljournal.com/pr/484834〕 On October 16, 2013, the company announced that InfiniDB would be licensed under the General Public License v. 2.〔http://infinidb.co/about/news/Calpont-Announces-New-Open-Source-Licensing-for-InfiniDB〕 Three open source versions of InfiniDB are available: InfiniDB, InfiniDB for the Cloud, and InfiniDB for Apache Hadoop 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「InfiniDB」の詳細全文を読む スポンサード リンク
