Kusukela esigabeni esinikeziwe, kukhishwe abathengi abasekelwayo bokusakazwa kweSpark. Zihlukanise ngekhoma.
Context:I-Spark Streaming isebenzisa ikhono lokuhlela okusheshayo le-Spark Core ukwenza ukuhlaziywa kokusakazwa. It ingests idatha e mini-amaqembu futhi wenza RDD ukuguqulwa kulezi mini-amaqembu idatha. Lo mklamo uvumela isethi efanayo yekhodi yesicelo ebhalelwe ukuhlaziywa kwe-batch ukuthi isetshenziswe ekuhlaziyeni kokusakazwa, ngaleyo ndlela kube lula ukuqaliswa kokwakhiwa kwe-lambda. Kodwa-ke, lokhu kusebenziseka kahle kuza nesijeziso sokubambezeleka esilingana nesikhathi se-mini-batch. Ezinye izinjini zedatha yokusakaza ezicubungula umcimbi ngomcimbi kunamaqoqo amancane zifaka iStorm kanye nengxenye yokusakaza yeFlink. I-Spark Streaming inokusekelwa okwakhelwe ngaphakathi kokudla okuvela kuma-sockets Kafka, Flume, Twitter, ZeroMQ, Kinesis, kanye ne-TCP / IP.  Ku-Spark 2.x, ubuchwepheshe obuhlukile obususelwa kuma-Datasets, obubizwa nge-Structured Streaming, obunesixhumi esibonakalayo esiphakeme futhi bunikezwa ukusekela ukusakazwa.  I-Spark ingasetshenziswa esikhungweni sedatha sendabuko kanye nasemafini.
