Adding mobile tech so they are aware, I am guessing we need to query for
that data in a more efficient fashion.

Had to kill queries, lest analytics-store grind to a

This last few days analytics-store replication has started to lag by some
hours. Currently s1 (enwiki) and s5 (dewiki, wikidatawiki) are most
affected. Eventlogging is not lagging, due to the nicely batched writes it
does now-a-days :-)
There are many slow queries running from the research user on stat1003,
referencing eventlogging tables like MobileWebDiffClickTracking*.
I'm not sure who belongs to them, or if they're new, or if they're safe
to kill, so this is mainly a heads-up email. Let us know if ops should kill
stuff to let the box catch up again.
