Partitioning is independent of serialization. The key data is serialized
using the serializer specified through the "key.serializer.class" property
in the Producer. It defaults to a no-op encoder if you don't specify one.
Here, since you want to use an integer key, you'd have to plug in an
Encoder that can serialize integer data to a byte array.
