Smarter put FSM coordinator selection

[Russell Brown]

Hi,
Just a quick post to share some work we’ve been doing at the NHS on Riak tail latencies for PUTS.

Here’s a blog post:

https://github.com/russelldb/riak_kv/blob/rdb/gh1661/docs/soft-limit-vnode.md

And here are the PRs:

https://github.com/basho/riak_core/pull/921
https://github.com/basho/riak_kv/pull/1670

We’re hoping to get this in the next release of Riak.

Let me know if you have opinions,

Cheers

Russell
