--------------------------------------
Summary: Validate user parameters as early as possible
Key: KAFKA-3936
URL: https://issues.apache.org/jira/browse/KAFKA-3936
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Matthias J. Sax
Assignee: Guozhang Wang
Priority: Minor
Currently, parameters handed in by the user via public API, are not validated.
For example {{stream.to(null)}} would fail when the underlying producer gets
instantiated. This result in a stack trace from deep down in the library,
making it hard to reason about the problem for the user.
We want to check all given user parameters as early as possible and raise
corresponding (and helpful!) exceptions to explain users what the problem is,
and how to fix it.
