      Description

      So, it seems that if I want to set a custom serializer class on the producer (in 0.8), I have to use a class that includes a special constructor like:

      public class MyKafkaEncoder<MyType> implements Encoder<MyType> {
      // This constructor is expected by the kafka producer, used by reflection
      public MyKafkaEncoder(VerifiableProperties props)

      { // what can I do with this? }

      @Override
      public byte[] toBytes(MyType message)

      { return message.toByteArray(); }

      }

      It seems odd that this would be a requirement when implementing an interface. This seems not to have been the case in 0.7.

      What could my encoder class do with the VerifiableProperties?
