In some cases we have page_id, in other cases we have nothing (like API requests)

Aren't we currently just storing pageID?

Oliver, the problem with "page_title OR page_id" instead of "always page_title and page_id if you have it" is what Andrew was addressing
above.
It means we have to query for page_title by id, and that means we need to keep an up-to-date copy of all mediawiki databases. And we have to be
able
to query that copy tens of thousands of times per second, which is
basically
not going to happen.
We just chatted in scrum of scrums about this, it looks like Adam's
going to
set up a meeting so we can talk more there. I agree with Adam that we
have
to have a short term solution for counting the new kinds of requests. A medium term solution so that we don't all go insane, and something to
shoot
for in the long term.

In the absence of all clients doing it, "if it has this x_analytics entry, don't bother with the complex regular expressions, if it doesn't, do" still works.

Yeah, doing this on the client could work, but would require *all* clients to actually do it. We also have metrics per entry point in RESTBase,
but
those are behind Varnishes and will only count Varnish cache misses. Without Varnish caching, this would be a solved problem ;)

This (making pageviews proactive) is a great idea, and we should
follow
through. Here's a simple start:
If your app/site/etc. is creating a request that it wants to count
as a
pageview, add an X-Analytics header with pageview_id=<page_id> or pageview_title=<page_title>
If we can make this change uniformly, I think we'd be in a very good place.

This is an excellent point. IIRC we'd been asking Apps to do this
for
kind of a while, so...
