Uyini umehluko phakathi kokuguqulwa nesenzo kuSpark?
Injini kaSpark yokubulala yakhelwe ukuba ibe nguLazy. Eqinisweni, wena kuqala ukwakha up izicelo zakho analytics / idatha processing ngokusebenzisa uchungechunge Transformations okuyinto ke kwenziwa Action  Ukuguqulwa uhlobo imisebenzi okuzokwenza ukuguqula idatha yakho RDD kusuka ifomu eyodwa kuya kwenye. Futhi uma usebenzisa lo msebenzi kunoma iyiphi RDD, uzothola RDD entsha idatha aguquliwe Operations like ibalazwe, isihlungi kukhona ukuguqulwa.  Ukuguqulwa kwakha ama-RDD komunye nomunye, kodwa uma sifuna ukusebenza nedatha yangempela, ngaleso sikhathi isenzo senziwa. Lapho isenzo senziwa ngemuva komphumela, i-RDD entsha ayenziwa njengokuguqulwa. Ex:- ukubala i-DF
