[~aniket0710] -- I think [~jbfletch] never got to open a PR for it. Maybe [~high.lee] wants to take it over (asked about it above).

> In [KIP-210|https://cwiki.apache.org/confluence/display/KAFKA/KIP-210+-+Provide+for+custom+error+handling++when+Kafka+Streams+fails+to+produce], an exception handler for the write path was introduced. This exception handler covers exception that are raised in the producer callback.
> However, serialization happens before the data is handed to the producer with Kafka Streams itself and the producer uses `byte[]/byte[]` key-value-pair types.
> Thus, we might want to extend the ProductionExceptionHandler to cover serialization exception, too, to skip over corrupted output messages. An example could be a "String" message that contains invalid JSON and should be serialized as JSON.
