I'm using super column keys in a super column.
So let's say your resource is "routerA."
Your data will be:
Row "routerA"
SuperColumn "Status"
SuperColumn key T0 (this morning)
Columns { status: connected, location: USA, ... }
SuperColumn key T1 (T0 + 10 seconds for example)
Columns { status: disconnected, location: Europe, ... }
SuperColumn key T2 (T1 + 10 seconds for example)
Columns { status: connected, ... } // no location specified
Then you can say "give me the latest super column key" (limit = 1,
order = reversed, start == end == 0) and you'll get T1.
