  • O a gagana lagolago e fa'aoga i Apache Spark?

Apache Spark o se faʻavae gaosiaina o faʻamatalaga i le taimi moni ma fa'amaumauga fa'amaumauga tetele ua maua le ta'uta'ua i tausaga talu ai nei. E ofoina atu le lagolago mo gagana polokalame eseese, e mafai ai ona maua e tagata atiaʻe e eseese manaʻoga ma manaʻoga. Lalo, matou te tuʻuina atu gagana lagolago mo le faʻaaogaina i Apache Spark:

  • Skala: Scala o le gagana autu polokalame faʻaaogaina e atiaʻe ai Apache Spark. Tuuina atu fa'amatalaga fa'aupu ma mea fa'atatau, fa'afaigofie ona fa'aoga pe a galue i voluma tele o fa'amaumauga. E le gata i lea, o Scala e fetaui lelei ma faletusi Java, e mafai ai ona e faʻaogaina le tele o galuega o loʻo avanoa.
  • Java: Apache Spark ua fausia i luga o le Java platform ma o lea e ofoina atu le lagolago atoatoa mo lenei gagana. Java o se tasi lea o gagana polokalame e sili ona faʻaaogaina i totonu o pisinisi ma maua ai le tele o faletusi ma meafaigaluega e mafai ona faʻaaogaina i le atinaʻeina o talosaga Spark.
  • python: E lauiloa tele le Python mo lona faigofie ma le faitau. Apache Spark ei ai le API i le Python e mafai ai e oe ona atiaʻe faʻamaumauga o faʻamaumauga i se auala faigofie ma vave. O lenei API e maua ai galuega uma e manaʻomia e faʻaogaina ma suia seti faʻamaumauga tetele.
  • R: R ose gagana fa'afuainumera fa'akomepiuta fa'aaoga lautele i su'esu'ega fa'amaumauga. Apache Spark ofo atu le lagolago mo R e ala i SparkR. O lenei faletusi e mafai ai e tagata faʻaoga R ona faʻaogaina le tufatufaina atu o le malosiaga o le Spark e faʻatino ai suʻesuʻega faʻamaumauga tetele.
  • SQL: O lo'o ofoina atu fo'i e Apache Spark le agava'a fa'asologa o fa'amaumauga fa'avae SQL. E mafai ai e tagata fa'aoga ona tamo'e SQL fesili tuusa'o i luga o fa'amaumauga tu'ufa'atasia i Spark, fa'afaigofie ona fa'avasega ma su'esu'e le tele o fa'amatalaga.
