I'm trying to gather some stats on the use of Echo notifications across wikis, and I'd like to join the `echo_events` table with the `user` table for a given wiki.
I can get `echo_events` on x1-analytics-slave, but *not* on analytics-store; I can get `user` on analytics-store, but *not *on x1-analytics-slave. This makes it impossible to join the two.
Is there some other machine where both the tables are present? If not, is there a good reason for this split?
