Hi Guido, > What's the latest non-standard version of this function? v3 right? If Basho > adds more versions to this, is this somewhere documented?

It works better than v2 for balancing nodes but it has a performance caveat with larger ring sizes, which is why we still default to v2. I will address the documentation issue of this, but for now the source code is the best documentation (see below for links). > As of the latest > http://docs.basho.com/riak/latest/ops/advanced/configs/configuration-files/ > both parameters have no default where my understanding is that the default > for both is v2. So in the typical case, the default will be v2, via the `default_wants_claim` and `default_choose_claim` functions in `riak_core_claim.erl`. If you’re running a legacy ring, it will default to v1 instead. https://github.com/basho/riak_core/blob/1.4.4/src/riak_core_claim.erl#L119-L125 https://github.com/basho/riak_core/blob/1.4.4/src/riak_core_claim.erl#L140-L146 I’ve put in a docs issue to get the documentation clarified. https://github.com/basho/basho_docs/issues/1017 Thanks, Alex
