> JavaDocs of KStream#ValueTransform incorrect
> --------------------------------------------
>
> Key: KAFKA-9533
> URL: https://issues.apache.org/jira/browse/KAFKA-9533
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.3.0
> Reporter: Michael Viamari
> Assignee: Matthias J. Sax
> Priority: Major
>
> According to the documentation for `KStream#transformValues`, nulls returned
> from `ValueTransformer#transform` are not forwarded. (see
> [KStream#transformValues|https://kafka.apache.org/24/javadoc/org/apache/kafka/streams/kstream/KStream.html#transformValues-org.apache.kafka.streams.kstream.ValueTransformerSupplier-java.lang.String...-])
> However, this does not appear to be the case. In
> `KStreamTransformValuesProcessor#process` the result of the transform is
> forwarded directly.
> {code:java}
> @Override
> public void process(final K key, final V value) {
> context.forward(key, valueTransformer.transform(key, value));
> }
> {code}
