Follows-up T128709: Segment Navigation Timing data by continent
The sampling is too low for this to be useful for the number of countries we currently track. I'd recommend we reduce it to just a handful of large countries on several different continents.
For anything else we can use on-off queries in the raw EventLogging data in MySQL or Hadoop, we need the fragmentation in Graphite for that, and isn't actually useful because there's less than 1 data point per minute for many of the countries.
