-------------------------------
Resolution: Invalid
> Kafka Stream ignores Serde exceptions leading to silently broken apps
> ---------------------------------------------------------------------
>
> Key: KAFKA-4146
> URL: https://issues.apache.org/jira/browse/KAFKA-4146
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.0.1
> Reporter: Elias Levy
> Assignee: Guozhang Wang
>
> It appears that Kafka Streams silently ignores Serde exceptions, leading to
> app that are silently broken.
> E.g. if you make use of {{Stream.throough("topic")}} and the default Serde is
> inappropriate for the type, the app will silently drop the data in the floor
> without even the courtesy of printing a single error message.
> At the very least an initial error message should be generated, with the
> option to generate messages for each such failure or a sampling of such
> failure.
