Hi guys, Any updates on these questions?
I’ve read the following blog entry http://basho.com/blog/technical/2012/07/02/folsom-backed-stats-riak-1-2/ and still haven’t found the answers. As far as I understand riak_core_stat_cache caches stats using ets, so I’m wondering why statistics that is stored in ets is cached using ets? Is it correct that calls to folsom_metrics are done via gen_server to decrease the possibility of losing ets tables that are bound to a concrete process?

I’d like to use the same library (folsom) in my application so could you answer the following questions: 1. Why separate gen_servers (riak_api_stat, riak_core_stat, riak_kv_stat) were used to gather statistics instead of the direct calls to folsom_metrics through some more high-level api? 2. What is the purpose of riak_core_stat_cache and what it is intended to do?
