Apache Impala shine buɗaɗɗen tushe mai daidaitawa daidai gwargwado (MPP) injin tambaya na SQL don bayanan da aka adana a cikin tarin kwamfuta mai gudana Apache Hadoop . An bayyana Impala a matsayin tushen budewa daidai da Google F1, wanda ya karfafa ci gabansa a cikin 2012. 

 Bayani 
Apache Impala injin tambaya ne wanda ke gudana akan Apache Hadoop. An sanar da aikin a cikin Oktoba 2012 tare da rarraba gwajin beta na jama'a kuma ya zama gabaɗaya a cikin Mayu 2013. 

Impala yana kawo fasahar bayanai mai daidaitawa zuwa Hadoop, yana bawa masu amfani damar ba da ƙananan tambayoyin SQL zuwa bayanan da aka adana a HDFS da Apache HBase ba tare da buƙatar motsin bayanai ko canji ba. An haɗa Impala tare da Hadoop don amfani da fayil iri ɗaya da tsarin bayanai, metadata, tsaro da tsarin sarrafa albarkatun da MapReduce, Apache Hive, Apache Pig da sauran software na Hadoop ke amfani da su.

Ana ciyar da Impala ga manazarta da masana kimiyyar bayanai don yin nazari akan bayanan da aka adana a Hadoop ta hanyar SQL ko kayan aikin sirri na kasuwanci . Sakamakon shi ne cewa manyan bayanan sarrafa bayanai (ta hanyar MapReduce) da kuma tambayoyin hulɗa za a iya yin su akan tsarin guda ɗaya ta amfani da bayanai iri ɗaya da metadata - cire buƙatar ƙaura saitin bayanai zuwa tsarin na musamman da / ko tsarin mallakar mallaka kawai don yin bincike.
