Ingabe i-spark inikeza usuku nesikhathi lapho umcimbi othize utholakala ekusakazeni okuhlelekile?
Hhayi ngokuqondile. Umthombo wedatha unesibopho sesikhathi sesigameko, isikhathi <unk>sokufika<unk> ngokuvamile yisikhathi esivela kumthombo wesiphakeli somlayezo owufundayo (uKafka, Kinesis, njll.) kanye nesikhathi <unk>sokucubungula<unk> singafakwa lapho kusetshenzwa ngokusakazwa kwedatha engenayo kusetshenziswa iphakethe lemisebenzi current_timestamp function. https://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.sql.functions$ Lokhu akuyona ngempela isikhathi lapho iSpark ithola khona idatha kusuka kuseva kodwa iseduze futhi izoqoqwa ngezikhathi zokuqala. Qaphela ukuthi lo msebenzi awukwazi ukusetshenziswa uma usesimweni esiqhubekayo. https://spark.apache.org/docs/latest/structured-streaming-programming-guide.html#supported-queries
