-- Imported data into postgresql running locally. For larger data sets I would go the map reduce route, seemed overkill here.
-- All of the questions are answered with sql - I did end up double checking some of the results with python - happy to provide that code on request.


-- Consider only the rows with country_id = "BDV" (there are 844 such rows).
-- For each site_id, we can compute the number of unique user_id's found in these 844 rows.
-- Which site_id has the largest number of unique users? And what's the number?


SELECT x.site_id, COUNT(x.site_id) as site_count
