When we started we were sqooping at the beginning of the month and the processing takes something like 4 days total, most of it sqooping.  But this put too much load on the database serves too close to the beginning of the month when a bunch of other stuff is running.  So we had to move it back to the 5th of the month [1].  Add 4 days onto that and we end up finishing around the 9th of the month.  We don't like this at all and we're trying to figure out a better way to import the data incrementally so we can just start processing when we have all of it.  It's unfortunate but we couldn't foresee the infrastructure limitation, too much was up in the air about even where we would sqoop from when we started this work.  Joseph and I have a weekly meeting to discuss moving towards a more incremental approach, and this task is the parent task to watch for now: https://phabricator.wikimedia.org/T193650 (priority is low because we have too many other commitments, but it's something I'd love to see before we call wikistats 2 "production" quality)
