I roto i te 2004, whakaputaina Google he pepa i runga i te tukanga i huaina MapReduce e whakamahi i te hoahoanga rite. whakarato te ariā MapReduce he tauira tukatuka hāngai, a ka tukua he whakatinanatanga e pā ana ki ki te tukatuka nui o te raraunga. Ki te MapReduce, ngā uiuinga e wehea, ka tohaina puta noa i ngā kōpuku hāngai, me te tukatuka i roto i te hāngai (te Hipanga Map). ka kohikohia nga hua, ka tukua (te Hipanga whakaiti). i tino angitu te anga, na hiahia ana ētahi atu ki te tārua i te hātepe. Na reira, i whakaaetia te whakatinanatanga o te anga MapReduce e te kaupapa tuwhera-pūtake Apache huaina Hadoop. i whakawhanakehia Apache Spark i roto i 2012 i roto i te whakautu ki ngā herenga i roto i te MapReduce tauira, rite tāpiri te reira i te kaha ki te whakaturia ake maha mahi mahere (e kore e tika na roto i te whakaiti). pātai: He aha te whakaaro ki te whakapai ake i te tukanga raraunga hou
