Null Output topic for Kafka Streams

[David Garcia <da...@spiceworks.com>]

I would like to process messages from an input topic, but I don’t want to send messages downstream…with KStreams.  (i.e. I would like to read from a topic, do some processing including occasional database updates, and that’s it…no output to a topic).  I could fake this by filtering out all my messages, and specify a fake topic…but I was wondering if there is a less hacky way to do this.  Thx!

You can use KStream#foreach() as last operator.
