OK, long explanation below. You've uncovered a wart.
By default every store and fetch operation requires a Converter<T> to be
present. And, to make life easy, by default, I provide the JSONConverter<T>,
that converts the object it is given to JSON. This is a problem if you use the
raw IRiakObject type since the whole thing gets serialised, rather than just
the values. The fix, which I have, is to check the type, and if it is
IRiakObject then don't use the converter. The longer term fix is to have a
registry of converters mapped to types, but that is not done yet.
The problem really is that the higher level API expects you to store domain
things, not lower level, Riak things.
I know this seems bad, but I wanted an API that gave a flexibility *and* pushed
people towards using domain specific classes, since handling conflicts requires
that. It does mean there is this slightly more verbose hoop to jump through
when you want to use a plain IRiakObject from the higher level client API.
TL;DR
Store a domain specific java object with two fields, `email` and `pass` OR
provide a PassThroughConverter to the StoreOperation OR if you are dealing
directly with IRiakObject, use RawClient. I'm working on a silent solution that
detects the IRiakObject type and does not convert it.
Does it make sense?
