Why do you specifically want SDB -- sounds like you already have your data in a MySQL database or something like it, and, the code can already use data in a database table. > Would something like this work in TASTE.

Yes, doesn't work if you need prefs to immediately reflect new data, but there are situations where that is not the case. The batch-oriented Hadoop/EC2 bindings are for those cases. The core code, however, is for the sort of real-time situation you describe.
