Hi Again,

@Dan: We will indeed reload data into cassandra.

@Bo: Actually the two datasets are fairly different.
The one called pagecounts is slowly getting deprecated toward the one called pageview, defined by Research people at WMF: https://meta.wikimedia.org/wiki/Research:Page_view
The pageview dumps are actually a 'legacy format' view of the new pageview :)

Code for the legacy extraction: https://github.com/wikimedia/analytics-refinery/blob/master/oozie/pagecounts-all-sites/load/insert_hourly_pagecounts.hql
Code for the new pageview definition: https://github.com/wikimedia/analytics-refinery-source/blob/master/refinery-core/src/main/java/org/wikimedia/analytics/refinery/core/PageviewDefinition.java
