Hi Sergey,

We (OpenX) have a riak_core based application that's running on a 125 node =
cluster (there are also other smaller clusters). We never really tested to =
see where it would fall over (and the cluster was much smaller when it star=
ted), but I see no indicators that it will fall over when we add the 126th =
node. FWIW, it's running riak_core 0.13.0, and I assume the newer versions =
of riak_core have only gotten better. Answers to some of your other questio=
ns (based solely on my experience) in-line below.

The riak list mentioned optimism about riak clusters of 200+ nodes in a thr=
ead here:
http://riak-users.197444.n3.nabble.com/does-Riak-cluster-maintain-fully-con=
nected-Erlang-network-td3695942.html

However, as mentioned in the thread, a fully connected network of nodes (fu=
lly connected because of the usage of distributed Erlang) does  have a natu=
ral limit (due to the network speed) on scalability with the net tick time.=
  You can always increase the net tick time, but then failures will take lo=
nger to detect.

So, your success may rely on your fault-tolerance requirements.
