java client

Since kafka is written in scala, when using a java client (producer or
consumer), do you pay a slight performance hit because you guys are
internally mapping back/forth to map a java type to a scala type?

We haven't really measured the scala overhead. However, my guess is that it
should be small compared to the network overhead, which one has to pay for
each request.

Thanks,
