Nice, thank you for reply. So if I call slotSharedGroup(groupname) on the last operator as here:
DataStream<MyEvent> stream = env .addSource(new FlinkKafkaConsumer010<>(TOPIC, new CustomDeserializer(), properties)) .assignTimestampsAndWatermarks(new CustomTimestampExtractor()) .map(...) .slotSharingGroup("source"); it is applied to all the previous operator right? Or I have to call it after each operator? i.e I want that addSource, assignTimestamp and map reside on the same slot. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
