---------------------------------
Summary: 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.
