How much data do you think you will need ad hoc query ability for?

It won't cause hotspots as long as you are sharding by a small enough
time period, like hour, day, or week.
I.e. the key is the hour day or
How many total ranges to you expect to have long term?

Ed,
I could be completely wrong about this working--I haven't specifically
looked at how the counts are executed, but I think this makes sense.
You could potentially shard across several rows, based on a hash of
the username combined with the time period as the row key. Run a
count across each r

Depending on how often you have to write to the database, you could
perform dual writes to two different column families, one that has
summary + details in it, and one that only has the summary.
This way you can get everything with one query, or the summary with
one query, this should als
performed the most, and how important they are. I think that would
help anyone recommend a path to take.

Matthias,
This is an interesting problem.
I would consider using long's as the column type, where your column
names are evenly distributed longs in sort order when you first write
your list out. So if you have items A and C with the long column
names 1000 and 2000, and then you have to insert B,
