Since you're writing/reading all of the subcolumns at the same time, I would opt for a standard column with the tags serialized into a column value. I don't think you need to worry about row lengths here. Depending on the reminder size and how many times it's likely to be repeated in the timeline, you could explore denormalizing a bit more by storing the reminders in the timelines themselves, perhaps with a separate row per (user, tag) combination. This would cut down on your seeks quite a bit, but it may not be necessary at this point (or at all). -- Tyler Hobbs Software Engineer, DataStax <http://datastax.com/> Maintainer of the pycassa <http://github.com/pycassa/pycassa> Cassandra Python client library
