CipherStash - specifically the key service. There is a lot of data for sure but we only record an identifier for each value and (optionally) the user ID. It compresses well.
So an identifier is kept for each column returned by a query?
If the value changes would you be able to get from the id you have audited back to the value that was returned at that point in time?
