I'm currently migrating Java client from 1.4 to 2.1 and I have a question
about RiakCluster class.
We hide Riak Java API by our interface since we use multiple backends and
Riak is one of them.
Let's say I have two independent business activities that makes calls to
Riak cluster. Both activities
are outlined in the documentation here:
http://docs.basho.com/riak/latest/upgrade-v20/
Thanks to CMJ for reminding me of these details.

Just want to check if I understand the documentation correctly. In order to
upgrade my cluster I from version 1.2.1 to 2.1.1 I need to do two steps of
the rolling upgrade:
1) 1.2.1 -1.4.12
2) 1.4.12 - 2.1.1
Is it correct?

Sorry jumping into the discussion. What is a best way to monitor Riak node
health? Most loadbalancer uses HTTP request to check if a node is alive.
Currently we use Riak Java client to load balance requests to Riak. The issue
is if a node gets removed or added all Java servers need to update
nodes' health.
Metrics are available through the HTTP API via the /stats endpoint.
For details, see:

You need to call shutdown method of Riak client when you are stopping your
application.
Thank you,

We use riak 1.2.1 in production. Recently we had two incidents when a Riak
node (out of 27 nodes) was in limbo state: riak-core worked fine but
bitcask backend was constantly crashing (see below). Both times it happened
immediately after Riak was restarted due to Linux reboot.
I looked at the
I have built a production like prototype using riak-core. My major issue was
luck of documentation (out-dated or missing aspects). So I spent about 5-7 days
in reading source code and writing tests. I think a simple sequence digram of
hinted hand-off would answer on many my questions. Please
I used mochijson2 and ejson. I found that ejson works faster since it's
built using NIF. But both libraries use tuple wrapping around proplists.
Thus I developed a few wrapper functions to manipulate with fields.
Thank you,
Konstantin.

Looking at http://docs.basho.com/riak/latest/references/Client-Libraries/ I see
that Erlang riak client should support Cluster connections/pools. But looking
at Erlang riak client source code I would say that it doesn't support Cluster
connections/pools out of box. And I have to develop my own
