Usebenza njani uSpark?

Usebenza njani uSpark? ngomnye wemibuzo abantu abaninzi be-IT abazibuza yona xa bezama ukuqonda ukuba lisebenza njani eli qonga linamandla lokusetyenzwa kwedatha. I-Spark sisikhokelo somthombo ovulekileyo ovumela ukusetyenzwa kweedatha ezininzi ngokukhawuleza nangokufanelekileyo. Ngokungafaniyo nezinye izixhobo, i-Spark isebenzisa imodeli yokusetyenzwa kwenkumbulo eyenza ukuba ifike kumaxesha ali-100 ngokukhawuleza kunesakhelo esifanayo. Kweli nqaku, siza kuchaza ngendlela elula necacileyo ukuba iSpark iyenza njani imisebenzi yayo kunye nendlela onokufumana ngayo okuninzi kuyo emsebenzini wakho wemihla ngemihla.

Usebenza njani uSpark?

• I-Spark yinkqubo enkulu yokucubungula idatha evumela ukuba uhlalutyo lwenziwe ngokukhawuleza nangokuchanekileyo.
• Isebenzisa i-injini yokucubungula inkumbulo, iyenza ifikelele kumaxesha angama-100 ngokukhawuleza kuneHadoop, ngakumbi kwimisebenzi yebhetshi kunye nexesha langempela lokucubungula idatha.
• I-Spark yenziwe ngeemodyuli ezininzi, kuquka i-Spark SQL, i-Spark Streaming, i-MLib kunye ne-GraphX., ikuvumela ukuba usebenze ngeentlobo ezahlukeneyo zedatha kwaye wenze imisebenzi eyahlukeneyo yokucwangcisa kunye nokuhlalutya.
• Indlela esebenza ngayo iSpark isekwe ekudalweni kwegrafu yokusebenza, ebizwa ngokuba yiResilient Distributed Dataset (RDD)., ekuvumela ukuba usasaze idatha ngapha kweqela kwaye wenze imisebenzi ngokuhambelana.
• Ukusebenzisana neSpark, ungasebenzisa i-API yayo kwiJava, Scala, Python okanye R, okwenza ukuba kufikeleleke kwiintlobo ezahlukeneyo zabaphuhlisi kunye nososayensi bedatha.

Q&A

Usebenza njani uSpark?

1. I-Spark isebenza nge-injini yokucubungula esasazwayo evumela uhlalutyo lwedatha ehambelanayo.

2. Isebenzisa ingcamango ye-RDD (i-Resilient Distributed Dataset) ukugcina nokucubungula idatha ngendlela yokusabalalisa kwi-cluster of machines.

3. I-Spark ineemodyuli zokwenza uhlalutyo lwexesha langempela, i-batch data processing, kunye nokufunda ngomatshini.

4. Ukongeza, iSpark ibandakanya amathala eencwadi okusebenza neenkcukacha ezicwangcisiweyo, ezifana neSQL, iDathaFrames, kunye neeDatha zeDatha.

5. I-architecture yayo yenziwe ngumphathi weklasta (onjengeYARN okanye iMesos), umphathi wezibonelelo, kunye nabenzi bokufa abasasazwa kwiinodi zeklasta.

6. Nje ukuba ifakwe kwaye iqwalaselwe kwiqela, iSpark inokudityaniswa nayo ngojongano lomgca womyalelo okanye ngeenkqubo ezibhalwe ngeelwimi ezinjengeScala, Java, Python, okanye R.

7. Intlantsi inokuqhutywa ekuhlaleni ngeenjongo zophuhliso okanye kwiqela lokuphatha umthamo omkhulu wedatha.

8. Ibonelela ngeendlela zokuphucula ukusebenza kakuhle, njengokucwangcisa umsebenzi, ukusetyenziswa kwakhona kwedatha kwimemori, kunye nokunyamezela iimpazamo.

9. Uluntu lwaseSpark luyasebenza, lubonelela ngenkxaso, amaxwebhu, nentaphane yezibonelelo zemfundo ukufunda indlela yokusebenzisa iqonga.

10. Okokugqibela, iSpark isetyenziswa kumashishini ahlukeneyo, kubandakanywa iteknoloji, imali, ukhathalelo lwempilo, kunye nonxibelelwano lomnxeba, kuhlalutyo olukhulu lwedatha kunye nokucubungula.
