Apache Spark ke moralo ts'ebetso ea data ka nako ea 'nete le litlhahlobo tse kholo tsa data tse fumaneng botumo lilemong tsa morao tjena. E fana ka ts'ehetso bakeng sa lipuo tse fapaneng tsa mananeo, e etsa hore e fumanehe ho batho ba ntlafatsang ba nang le likhetho le litlhoko tse fapaneng. Ka tlase, re hlahisa lipuo tse tšehetsoeng hore li sebelisoe ho Apache Spark:

• Sekala: Scala ke puo ea mantlha ea mananeo e sebelisoang ho nts'etsapele Apache Spark. E fana ka syntax e khuts'oane le ntho e sekametseng, ho etsa hore ho be bonolo ho e sebelisa ha o sebetsa ka bongata bo boholo ba data. Ho feta moo, Scala e tsamaisana le lilaebrari tsa Java, e u lumellang ho nka monyetla ka mefuta e mengata ea ts'ebetso e fumanehang.
• Java: Apache Spark e hahiloe sethaleng sa Java mme ka hona e fana ka tšehetso e felletseng bakeng sa puo ena. Java ke e 'ngoe ea lipuo tse sebelisoang haholo indastering' me e fana ka lilaeborari tse ngata le lisebelisoa tse ka sebelisoang ho nts'etsapele lits'ebetso tsa Spark.
• python: Python e tsebahala haholo ka mokhoa o bonolo le o bonolo oa ho bala. Apache Spark e na le API ho Python e u lumellang ho nts'etsapele lits'ebetso tsa ts'ebetso ea data ka tsela e bonolo le e potlakileng. API ena e fana ka ts'ebetso eohle e hlokahalang ho laola le ho fetola li-data tse kholo.
• R: R ke puo ea lenaneo la lipalo-palo e sebelisoang haholo tlhahlobong ea data. Apache Spark e fana ka tšehetso bakeng sa R ​​ka SparkR. Laeborari ena e lumella basebelisi ba R ho phahamisa matla a ts'ebetso a ajoang a Spark ho etsa tlhahlobo e kholo ea data.
• SQL: Apache Spark e boetse e fana ka litsebo tse tsoetseng pele tsa SQL tse thehiloeng ho data. Sena se lumella basebelisi ho sebetsa Lipotso tsa SQL ka kotloloho ho li-dataset tse ajoang ho Spark, ho etsa hore ho be bonolo ho sekaseka le ho hlahloba lintlha tse ngata.

Kaha joale u se u tseba lipuo tse tšehetsoeng tse sebelisoang ho Apache Spark, u ka khetha e lumellanang hantle le litlhoko tsa hau mme u nke monyetla oa melemo eohle e fanoang ke moralo ona o matla oa ts'ebetso ea data.
