    RethinkDB Changfeeds and Plottico

This example shows how to take the output of a RethinkDB changefeed and send it to Plottico, a microservice that generates embeddable streaming graphs. This example uses Plottico's hosted infrastructure, but you can also self-host your own Plottico server using the code from Plottico's GitHub repository.

  
## demo.rb
require "net/http"
require "rethinkdb"

include RethinkDB::Shortcuts

conn = r.connect()
changes = r.db("rethinkdb").table("stats").get(["cluster"])
           .changes()["new_val"]["query_engine"].run(conn)

changes.each do |stats|
  data = [stats["queries_per_sec"],
          stats["read_docs_per_sec"],
          stats["written_docs_per_sec"]].join(",")
  Net::HTTP.get(URI.parse("http://plotti.co/mygraph?d=#{data}"))
end
