Anther point: while WDQS does fetch data from both clusters (at least is supposed to), it only tracks its timestamp by one topic: reportingTopic, which is currently eqiad.mediawiki.revision-create. Otherwise we get weird jumps in the timestamps, since different topics can get different events in different sequence. So if eqiad does not get any events, the updater seems to lag even though it is processing events from codfw. I am not sure whether "nothing useful" message is related anyhow.
