First, we are dealing with append-only data, where each column is
only ever
written once and never updated.
Will this always be the case? We do plan on using C* for future uses - I'm wondering
what happens if we do have data that will not be "append-only" in the future?
Should we leave code in here to prepare for that? Or will we always ensure any data we put
into C* fits this model of append-only (written once, never updated)?
