How will someone using kryo know which implementation to use? Can we add
some guidance around that?

> Reporter: Yuksel Akinci
> Priority: Major
>
> These changes add two new kryo serialization classes (KryoSimpleWritable and
> KryoSimpleWrapper) which disable reference tracking at the expense of not
> supporting recursive and nested structures. Disabling reference tracking
> significantly improves the serialization performance. One a sample pipeline,
> the running time reduced from 75 minutes to 5 minutes.
