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.

It naturally has a timestamp as one of its attributes, 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. -Brandon
