> Exploit #peek to implement #print() and other methods
> -----------------------------------------------------
>
> Key: KAFKA-4772
> URL: https://issues.apache.org/jira/browse/KAFKA-4772
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Matthias J. Sax
> Priority: Minor
> Labels: beginner, newbie
>
> From: https://github.com/apache/kafka/pull/2493#pullrequestreview-22157555
> Things that I can think of:
> - print / writeAsTest can be a special impl of peek; KStreamPrint etc can be
> removed.
> - consider collapse KStreamPeek with KStreamForeach with a flag parameter
> indicating if the acted key-value pair should still be forwarded.
