Nje ukuba ube nokuqonda okusisiseko kojongano, unokuphonononga imisebenzi eyahlukeneyo enikezelwa nguSpark. Oku kubandakanya ukusebenzisa izixhobo zokuhlalutya idatha, ezifana neegrafu kunye neetshathi, ukujonga kakuhle nokuqonda idatha. Ukongeza, kuyacetyiswa ukuba kusetyenziswe izixhobo ezifumanekayo zokucwangcisa kunye nezixhobo ezizenzekelayo ukwandisa ukusebenza kakuhle kunye nemveliso.

Isindululo esiphambili sokufumana okuninzi kwiphepha le-Spark kukusebenzisa imizekelo kunye nezifundo ezibonelelweyo. Ezi zifundo zezifundo zikunceda uqonde indlela amandla e-Spark asetyenziswa ngayo kwiimeko zelizwe lokwenyani kwaye anike izimvo malunga nendlela yokuwasebenzisa ngokufanelekileyo. Ukongeza, kuyacetyiswa ukuba uhlale unolwazi ngohlaziyo kunye neempawu ezintsha ezongeziweyo kwiphepha, njengoko oku kunokwandisa ngakumbi iinketho kunye namathuba okusebenzisa iSpark.

Isishwankathelo, imida yephepha leSpark linokwahluka ngokuxhomekeke kwiimfuno zomsebenzisi ngamnye kunye noqwalaselo. Nangona kunjalo, kukho imida yobugcisa kunye nokusebenzayo ekufuneka kuthathelwe ingqalelo xa usebenzisa eli qonga.

Okokuqala, omnye weyona mida ixhaphakileyo inxulumene nobungakanani bedatha enokucutshungulwa kwiqela elinye leekhompyuter. Njengoko umthamo wedatha ukhula, imiba yokusebenza inokuvela kwaye amaxesha okusebenza anokwanda. Ke ngoko, kubalulekile ukuvavanya amandla ezibonelelo zakho kunye nokulungelelanisa izixhobo ngokufanelekileyo.

Ukongeza, nangona i-Spark isaziwa ngokukwazi ukusebenza ngomthamo omkhulu wedatha, kusenokubakho imisebenzi ethile engenzekiyo ngenxa yokunqongophala kwememori okanye izixhobo zokubala. Kule meko, kuyacetyiswa ukuba uhlukanise imisebenzi ibe ngamanyathelo amancinci okanye ucinge ngezinye iindlela.

Ugcino lunokuba ngumda kwimeko yeSpark. Ngokuxhomekeke kuqwalaselo kunye nobungakanani beqela lakho, unokuhlangabezana nezithintelo zomthamo wokugcina. Kubalulekile ukubeka iliso nokulawula indawo ekhoyo ukuthintela iingxaki zokunqongophala kwendawo.

Ukongeza, i-algorithms ye-Spark-specific kunye nemisebenzi inokuba nemida yendalo ngokwemiqathango yokulinganisa kunye nokusebenza kakuhle. Eminye imisebenzi ingantsonkotha ngakumbi kwaye ifune izixhobo ezingaphezulu zokwenziwa, nto leyo enokuchaphazela amaxesha okuphendula.

Ekugqibeleni, ukuqonda imida yobugcisa yePage Spark kubalulekile ekufumaneni okuninzi kweli qonga lokucwangcisa idatha. Ngokuvavanya kunye nokulungelelanisa izixhobo ngokufanelekileyo, kunye nokuqhawula imisebenzi ibe ngamanyathelo amancinci xa kuyimfuneko, abasebenzisi banokunqoba ezininzi zezi zithintelo kwaye bafezekise iziphumo ezisebenzayo.
