At some point I heard that Flow data is in the x1 shard.
But I actually never had to work with that data, so that information
might be stale.

Just in case ... we have a separate slave for x1:

  x1-analytics-slave.eqiad.wmnet

. And that shard has a flowdb with (it seems) flow related tables [1]
with recent timestamps [2].

We previously could connect to that slave from stat1003, but that did
no longer work when I tried just now :-/
That might be related to yesterday's vlan move of stat1003, so I filed
T84990 [3] to open up the firewall to the x1 slave again.

Have fun,
Christian
