@Dušan Kreheľ: I think there's a misunderstanding. I read your re-written article. In it, you say that the current format is:
domain_code page_title count_views total_response_size
For an example, you give this:
sk Kreheľ 2 0
But, actually, that format is deprecated and the new format is pageviews complete, which looks like this:
sk.wikipedia Kreheľ null desktop 13 B2D2G2J2O2T1V1X1
The B2D2G2J2O2T1V1X1 is exactly the kind of encoding you're talking about, and no 0-values are present.
You made the point that we are missing a yearly rollup in this new format. This would be quite a large file, but if there's a good use case for such a dump, a request in phabricator is a good way to proceed.
