    bucket_props => {
        "r" => "one"
        "w" => "one"
        "dw", "one
     }
or
[source,ruby]

  * Default value is `{"localhost"=>"8098"}`

The nodes of your Riak cluster
This can be a single host or

    {
        "node1" => "8098"
        "node2" => "8098"
    }

[id="plugins-{type}s-{plugin}-proto"]

SSL Options
Options for SSL connections
Only applied if SSL is enabled
Logstash hash that maps to the riak-client options
here: https://github.com/basho/riak-ruby-client/wiki/Connecting-to-Riak
You'll likely want something like this:

[source, ruby]
    ssl_opts => {
       "pem" => "/etc/riak.pem"
       "ca_path" => "/usr/share/certificates"
    }

Per the riak client docs, the above sample options
will turn on SSL `VERIFY_PEER`
