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
started), but I see no indicators that it will fall over when we a
I'm trying to understand when and how data handoff between nodes is
triggered in riak_core. I was under the impression that data would be
shuffled when a new node joined the cluster or an existing node left the
cluster, but maybe that's not the case? It looks like joining a cluster is
accomplished

Hi,
I've got a riak_core application based on 0.13.0 that I'm updating to
riak_core 1.0. In the process, I thought I'd try moving it from framewerk
to rebar. For my initial attempt I used the riak_core template, but when I
tried to build a release with reltool I got the following error:
[root@roc
t; are asking, but hopefully this helps you some in tracking down the issue.

Hello,
I'd like to capture statistics on all calls to my riak_core service and the
execution time of vnode commands. I looked at folsom_metrics, but for a
service that does 10-30k QPS I'm concerned about the overhead introduced of
doing ets calls. Given that, my current plan was to create several
sho_metrics_nifs:histogram_stats(MGStat).
** exception error: bad argument
in function basho_metrics_nifs:histogram_stats/1
called as basho_metrics_nifs:histogram_stats(<<>>)

It looks like storing the refs in an ets table works, so I'll try that.
Thanks,
Joel
