Over several stages we'll want to turn on the VirtualPageView schema to all wikis. We'll want to leave at least a day between each.
Currently it is only live on Hungarian Wikipedia, where we are seeing 4 events per second.
We estimated that recording a page interaction when a preview has been open for > 1000 ms will correspond to an increase in webrequests per pageview of 0.13%, which corresponds to ~700-800 events/sec (or, roughly, 2x the peak rate from the Page Previews instrumentation). AIUI the Hive EventLogging backend can handle this event rate 💪 but the processors need to be monitored to see if more need to be added.
Roll out plan
- s6.dblist (fr, ja and ru wiki)
- wikipedia.dblist - top6-wikipedia.dblist (all but the top 6 wikipedias)
- All wikis
For each roll out:
