Could you look at the cassandra log? This is probably due to an
error on the server side.

Hello,
Sorry,It is right that you say so.
Checking data is very difficult.
But, If the writing of data is returned correctly,
one or more data is written certainly on Cassandra.
Therefore,
If you didn't set read_repair_chance lowered,
I think that it is the right way that you count on Read
My understanding is that support for super columns will remain within the
thrift API for the foreseeable future (perhaps indefinitely?) but under the
covers, super column families will get transitioned to regular column
families with composite column names (
We should be able to:
- find all time records from all users within a given project (with
optionally a certain date range)
- find total time per task
- find all time records from user X (with optionally a certain date range)
As I understand from your answer this would require atleast 3 (or 5?)

After re-reading my post, what I meant to say is that I switched from

saw better performance, but still far worse than no caching at all:

Running on cassandra 0.8.(6|7), I have issued two moves in the same cluster

Did I just trash my cluster ?

You are supposed to not be able to read it. But you should be getting

You'll need a timeline per project. I would use one row per day, week, or
