Thanks for the extensive answer. We buy a lot of data that comes in four times a year for our interactive mapping engine. Initially I would only want to update that data every quarter. That said, if I get a system like this up and running, there are other datasets that would be ideal in a system like this that would require quite a few writes every a day. Logs, cached images, etc.
