Objavljeno<\/a><\/noindex> o otvaranju izvornog koda SQL motora BlazingSQL<\/a><\/noindex>, koji koristi GPU za ubrzanje obrade podataka. BlazingSQL nije potpuna DBMS, ve\u0107 se pozicionira kao motor za analizu i obradu velikih skupova podataka, usporedan po svojim zadacima s Apache Spark<\/a><\/noindex>. Kod je napisan na Python jeziku i otvoren<\/a><\/noindex> pod licencom Apache 2.0. <\/p>\n

BlazingSQL je prikladan za izvr\u0161avanje pojedina\u010dnih analiti\u010dkih upita na velikim skupovima podataka (desetine gigabajta), pohranjenim u tabelarnim formatima (npr. logovi, statistike NetFlow itd.). BlazingSQL mo\u017ee provoditi upite iz raw datoteka u CSV i Apache Parquet formatima, smje\u0161tenim u mre\u017enim i obla\u010dnim datote\u010dnim sustavima, poput HDFS i AWS S3, izravno prenose\u0107i rezultate u memoriju GPU-a. Zahvaljuju\u0107i paralelizaciji operacija na GPU-u i kori\u0161tenju br\u017ee video memorije, izvr\u0161avanje upita u BlazingSQL odvija se do 20 puta<\/a><\/noindex> br\u017ee nego u Apache Spark.<\/p>\n

\"Otvoren<\/a><\/noindex><\/center><\/p>\n

Za rad s GPU-om koristi se razvojni paket otvorenih<\/a><\/noindex> biblioteka RAPIDS<\/a><\/noindex>, koji omogu\u0107uje kreiranje aplikacija za obradu podataka i analitiku, koje se izvr\u0161avaju isklju\u010divo na strani GPU-a (dostupan je Python su\u010delje<\/a><\/noindex> za kori\u0161tenje niskorazinskih CUDA primitiva i paralelizaciju izra\u010duna). <\/p>\n

BlazingSQL omogu\u0107uje kori\u0161tenje SQL-a umjesto API-ja za obradu podataka cuUDF<\/a><\/noindex> (na osnovi Apache Arrow<\/a><\/noindex>), primjenjivanog u RAPIDS-u. BlazingSQL predstavlja dodatni sloj koji radi iznad cuDF i koristi biblioteku cuIO za \u010ditanje podataka s diska. SQL upiti se prevode u pozive funkcija cuUDF, omogu\u0107uju\u0107i u\u010ditavanje podataka u GPU i izvr\u0161avanje operacija spajanja, agregacije i filtriranja. Podr\u017eava se kreiranje distribuiranih konfiguracija koje pokrivaju tisu\u0107e GPU-a. <\/p>\n

BlazingSQL zna\u010dajno pojednostavljuje rad s podacima \u2014 umjesto stotina poziva funkcija cuDF, mo\u017eete se poslu\u017eiti jednim SQL upitom. Kori\u0161tenje SQL-a omogu\u0107uje integraciju RAPIDS-a s postoje\u0107im analiti\u010dkim sustavima, bez potrebe za pisanjem specifi\u010dnih procesora i bez me\u0111uspojnog u\u010ditavanja podataka u dodatnu SBD-a, ali
\nu isto vrijeme zadr\u017eavaju\u0107i potpunu kompatibilnost sa svim dijelovima RAPIDS-a, prevode\u0107i postoje\u0107u funkcionalnost u SQL i osiguravaju\u0107i performanse na razini cuDF-a. Osigurana je i podr\u0161ka za integraciju s bibliotekama XGBoost<\/a><\/noindex> i cuML<\/a><\/noindex> za rje\u0161avanje analiti\u010dkih i problema strojnog u\u010denja. <\/p>\n
