> Tracing CPU usage of a Avro performance benchmark showed a measurable amount of time in the {{String#getBytes()}} method.
> Every time a String is serialized to the underlying stream, it ends up performing an array instantiation and a array copy.
> Optimize this code path by introducing a scratch buffer that can be re-used instead of instantiating a new one every time.
