To accept different types of records from multiple topologies, ProducerRecord is defined without generics. The above interface method will have a default implementation which returns ProductionExceptionHandlerResponse.FAIL

 Proposed Proposed Changes

This implementation will override the new method, handleSerializationException, in the following class:

...

We'll implement the following error handling logic to the send in RecordCollectorImpl. The new method, handleSerializationException, in ProductionExceptionHandler will not be invoked whenfor

1. ClassCastException is thrown while serializing record key / value. We will continue to throw this exception and not invoke the new method.  This will allow the current behavior to continue as this can help identify misconfigured serdes 

It will be invoked for

1. Any other unchecked exceptions, that thrown during record key / value serialization.
   1. If the result is CONTINUE, log a note at WARN that we received that result and are not failing Streams as a result.
   2. If the result is FAIL, log a message at ERROR that we received that result and set sendException so Streams will fail.
