-----------------------------------
Summary: Improve Transformer interface JavaDoc
Key: KAFKA-7430
URL: https://issues.apache.org/jira/browse/KAFKA-7430
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 2.0.0, 1.1.1, 0.11.0.3, 0.10.2.2
Reporter: Eugen Feller
Currently Transformer JavaDoc mentions that it is possible to use both
ctx.forward() and returning a KeyValue(). It would be great if we could mention
that returning a KeyValue is merely a convenience thing. In other words,
everything can be achieved using ctx.forward():
"return new KeyValue()" and "ctx.forward(); return null;" are equivalent.
