StreamsBuilder builder = new StreamsBuilder(); KStream<String, String> textLines = builder.stream("word-count-input"); KTable<String, Long> wordCounts = textLines .mapValues(textLine -> textLine.toLowerCase()) .flatMapValues(textLine -> Arrays.asList(textLine.split("\W+"))) .selectKey((key, word) -> word) .groupByKey() .count(Materialized.as("Counts")); wordCounts.toStream().to("word-count-output", Produced.with(Serdes.String(), Serdes.Long())); builder.build();
