Sean,
I made a spreadsheet to help track what has been requested. https://docs.google.com/a/wikimedia.org/spreadsheets/d/1RAhDbppfWDQsUXXr7r_5...
Let us know if you need more information before before you can start deleting old records.

Sounds great, Sean! The following tables can be set to keeping 40 days of data:
MediaViewer_6054199 MediaViewer_6055641 MediaViewer_6066908 MediaViewer_6636420 MediaViewer_7670440 MediaViewer_8245578 MediaViewer_8572637 MediaViewer_8935662 MediaViewer_9792855 MediaViewer_9989959 MultimediaViewerAttribution_9758179 MultimediaViewerDimensions_10014238 MultimediaViewerDuration_8318615 MultimediaViewerDuration_8572641 MultimediaViewerNetworkPerformance_7393226 MultimediaViewerNetworkPerformance_7488625 MultimediaViewerNetworkPerformance_7917896
There's a good chance that some of the older ones will end up being empty, in which case they can be safely dropped.

We can trim down our team (multimedia)'s tables considerably by getting rid of data older than 30 days. This could even be done by a daily cron. How would we go about doing that? Should we be the ones taking care of it? I'm not sure that the DB credentials I currently have can delete content.
We can automate purging using the MariaDB using the Event Scheduler[1] if you guys want a once-off-set-and-forget solution. Eg:
CREATE TABLE purge_schedule ( table_name varchar(100) NOT NULL, days tinyint(3) unsigned NOT NULL );
Then for each EL table you would do:
INSERT INTO purge_schedule VALUES ('MultimediaTiming_7193302', 30);
The rest would be left to me, or rather, to a couple of stored procedures :-)
