I would say just to add long and Long for indexing (So it that it supports Long, Integer and their respective natives), using BigNumber subclasses have a different semantic and would restrict the developers when designing the Riak POJOs.

All points to 32 bits, at least for the Java client side (indexes can be of type Integer, not Long which is the 64 bits) Look for RiakIndex.java, that will give you some answers.

That's a mistake on the part of the client developer at that time (me). They should probably be BigInteger, since integers can be arbitrarily large in erlang. I'm pretty sure Brian Roach (the new, smarter, Java developer) is addressing this https://github.com/basho/riak-java-client/issues/112

I don’t know the exact answer though.

I would say yes... Probably, if you're on a 64bit system. . Unless you're shifting stuff through JavaScript in which case I doubt it. Cause last I checked, js don't speak 64bit int.

I apologize for asking this question if it's an FAQ or is documented somewhere, but I don't see anything specific mentioned about the size of integer indexes in 2i:

I certainly could dive into to source code to answer this question, but in case someone here knows, what's the size of an integer index in 2i? I'm hoping that the answer will be that it's 64 bits…
Thanks,
Berend
