> Wanted to suggest a small optimization.  It is quite common for applications to do a quick check (along with null-ness) for 0-length of string-typed fields.  Today's Utf8.length() implementation is:
> {code}return toString().length;{code}
> I believe this could easily get optimized to return this instead:
> {code}return length == 0 ? 0 : toString().length();{code}
> Thus avoiding the need to create the string representation for this common use case (and scenario).
