Christopher Tubbs commented on ACCUMULO-4376:
---------------------------------------------

Yeah,i haven't added this yet, I was just thinking it'd be good to coordinate, 
and maybe we skip a 1.9 release in favor of a 2.0 containing these additions. 
If it means this gets committed first and I move the new classes into the API 
module before release, that'd work for me. The only real change is that the API 
module won't have a hadoop dependency, so no Text factories in the new class. 
At least, that's what I was thinking.

> Introduce a Builders for "data" classes

> In looking at ACCUMULO-4375, I was a little frustrated at how we have 3x 
> constructors than Key really provides just to support {{byte[]}}, {{Text}}, 
> and {{CharSequence}} arguments. Additionally, the {{copy}} argument forces 
> the user to use the most specific (most arguments) constructor if they want 
> to avoid the copy. This makes constructing a Key from just a row while 
> avoiding a copy very pedantic.
> I think a KeyBuilder (or KeyFactory) class would be a big usability benefit 
> and reduce the amount of code that clients have to write to most efficiently 
> construct Keys.
