Brandon,
it won't work in my application, as I need a few indexes on attributes
of the job. In addition, a large portion of queries is based on key-value
lookup, and that key is the unique job ID. I really can't have data packed
in one row per day.
Thanks,
Maxim

Each row represents a computational task (a job) executed on the grid or in

representing the time of the last update. This timestamp
is used to group the data into "buckets" each representing one day in the
system's activity.
I create the "DATE" attribute and add it to each row, e.g. it's a column
{'DATE','20111113'}.
Hmm, so why is pushing this into the row key and then deleting the
entire row not acceptable? (this is what the link I gave would
prescribe) In other words, you bucket at the row level, instead of
relying on a column attribute that needs an index.
