Andrew,
Are you saying the apps have the option to skip providing one of page_title or page_id? I hope this is the case since I just came up with a scheme where we could avoid the second request when a page has only a single section, which we already get through the first (lead) request.
Yes to what Oliver said: The apps don't always know the page_id ahead of time (only sometimes). The best example where we don't know the page_id ahead of time is when someone searches for a term on Google search on an Android device, and gets directed to our Android app. The app only gets the URL of the page, which we then take to derive the wiki and page_title from.

It'll need to be, some requests don't know pageID in advance, which I think was the reason Apps initially didn't implement this.

page_id is the current key, so let’s keep that. page_title would be
good to
have too. Let’s make it an and/or.

Ideally the page id would be the way to go. From a client's perspective I prefer the page title since clients don't always know the page id ahead
of
time. (We could put that header into the second request of loading the
page
but I cannot guarantee that we we will always have a second request in
the
future.)

This (making pageviews proactive) is a great idea, and we should follow through. Here's a simple start:

If we can make this change uniformly, I think we'd be in a very good place.

I really think that apps and APIs should do something proactive to
tag
or log a pageview. With more ways of viewing content, it is going
to get
harder and harder to maintain a pattern based definition. A
pageview should
be an event that is logged, not something that is pattern matched
out of a
very noisy stream of data.
Most mediawiki requests do this now, via the page_id field in the X-Analytlics header, but we can’t use this for all pageviews because
APIs
are more complicated (e.g. more than one page can be served in a
single
request, etc.). In the longterm, there should be a pageview event
stream
just like rcstream! :)
This is an excellent point. IIRC we'd been asking Apps to do this for kind of a while, so...

Woah woah woah woah woah. By RESTBase do you mean Gabriel's RESTful service API?
Last time I checked that wasn't even consumed by HDFS. Is it now
being
consumed by HDFS?
More importantly the actual URLs are going to look /totally/ different. If we do not include RESTBase requests, we will miss the apps. If we /do/ include RESTBase requests we will not only have to rewrite the pageview definition for the apps to recognise the new
URL
scheme, we will also potentially have to rewrite every /other/ bit
of
the definition to /not/ incorporate those requests.
(I use "we" in a collective sense. This isn't my baby any more, although if Joseph et al want help with the refactor here I'm happy
to
spend my volunteer time on it).
But basically every other bit of your email is important but now secondary: this is a potentially massive change, all on its own,
even
without the link preview, even if the substance of the requests
going
to RESTBase were identical.
