Data can be transformed using a number of different operators▪ Some operations result in a new KStream object– For example, filter or map▪ Some operations result in a KTable object– For example, an aggregation operationExamples of stateless transformation operations:– filter– Creates a new KStream containing only records from the previous KStreamwhich meet some specified criteria– map– Creates a new KStream by transforming each element in the current stream intoa different element in the new stream– mapValues– Creates a new KStream by transforming the value of each element in the currentstream into a different element in the new streamCopyright– flatMap– Creates a new KStream by transforming each element in the current stream intozero or more different elements in the new stream– flatMapValues– Creates a new KStream by transforming the value of each element in the currentstream into zero or more different elements in the new stream
