Today, I'm going to look at registration rates and activation rates broken down by mobile/desktop. To do this, I'm going to make use of Schema:PageContentSaveComplete and Schema:ServerSideAccountCreation -- both of which record the mobile/desktop source.

It looks like we have registrations going back to July, 2013.

> select left(timestamp, 6) AS month, count(*) FROM ServerSideAccountCreation_5233795 GROUP BY 1;
+--------+----------+
| month  | count(*) |
+--------+----------+
| 201302 |     2468 |
| 201303 |   332050 |
| 201304 |   218731 |

We can go back to March, 2013 with the previous version of the schema. It looks like the change only affected a description.

OK. So now to gather monthly registration rates per wiki.

SELECT
        wiki,
        month,
        mobile,
        SUM(registrations)
FROM (
        (SELECT
                wiki,
                LEFT(timestamp, 6) AS month,
                event_displayMobile AS mobile,
                COUNT(DISTINCT event_userId) AS registrations
                FROM ServerSideAccountCreation_5487345
        WHERE event_isSelfMade = 1
        GROUP BY wiki, month, mobile)
        UNION ALL
        (SELECT
                wiki,
                LEFT(timestamp, 6) AS month,
                event_displayMobile AS mobile,
                COUNT(DISTINCT event_userId) AS registrations
        FROM ServerSideAccountCreation_5233795
        WHERE event_isSelfMade = 1
        GROUP BY wiki, month, mobile)
) AS wiki_month_registration_counts
WHERE month BETWEEN "201303" AND "201503"
GROUP BY wiki, month, mobile;

OK... That's running. Now to gather the edit data.

What? Did we really only enable PageContentSaveComplete at the end of 2013? I thought it had predated ServerSideAccountCreation. Looks like the revision history disagrees. Oh well. Mobile hasn't been around that long anyway.

Time to write the query. --Halfak (WMF) (talk) 16:26, 8 April 2015 (UTC)Reply

OK Query is:

SELECT
        wiki,
        LEFT(timestamp, 6) AS month,
        rev_user AS user_id,
        SUM(event_isMobile) AS mobile_edits,
        SUM(!event_isMobile) AS desktop_edits
FROM revision
INNER JOIN log.PageContentSaveComplete_5588433 ON
      event_revisionId = rev_id AND
      wiki = DATABASE()
WHERE
      rev_timestamp BETWEEN "201312" AND "201504" AND
      timestamp	BETWEEN	"201312" AND "201504";

Since the user_id field isn't in the schema, I need to join against each wiki's revision table. :( This is a good excuse to fix up the utility that enables that. --Halfak (WMF) (talk) 17:10, 8 April 2015 (UTC)Reply

https://github.com/halfak/Multiquery Done

Now to run that query against the whole set of DBs. --Halfak (WMF) (talk) 19:56, 8 April 2015 (UTC)Reply
