Thanks Felipe! Yes, I think this is a really interesting tool to explore.
Another quick example:
List articles attract between 2-3% of pageviews on the English Wikipedia:
SELECT SUM(requests)
FROM [fh-bigquery:wikipedia.pagecounts_20150715_14]
WHERE LEFT(TITLE, 8) = 'List_of_'
AND language = 'en'
244091
SELECT SUM(requests)
FROM [fh-bigquery:wikipedia.pagecounts_20150715_14]
WHERE language = 'en'
8870277
(Caveats: during one hour this Wednesday, using the old pageview
definition, i.e. not excluding spiders and bots, and relying on the
article name instead of categories.)
I understand Felipe has already been talking to the WMF Analytics
team, who are making major progress on
https://phabricator.wikimedia.org/T44259 currently.

Hi! I'm currently attending Wikimania (I have a session on Friday at
4.30pm).
Tilman Bayer suggested to share this tool and techniques here, so I am
following his advice :).
I've been using Google BigQuery for a while to analyze Wikipedia's publicly
available data. It's main advantages:
- It's unbelievable fast (try it - operations that you might expect to run
in minutes or hours run in seconds).
- It's secure, but you can also instantly share data (no need to download
and setup locally before being able to analyze - BigQuery is always on).
- Everyone can use BigQuery with a free quota of 1TB of monthly analysis.
Interesting links:
- Quick getting started:

I have a couple other interesting examples I haven't written about, but the
invitation here is for you to try your own :).
My main challenge today: How to get more publicly available data into
BigQuery. Let's work together :). I'm sitting around the big data analytics
team today at the Wikimedia hackathon - and as said earlier, I'll do a
session on this topic on Friday at 4:30pm.
Thanks!
