Hi Jonathan,

In my case, I'll have much more columns (thousands to millions) than keys in logs (campaign x days), so it's not an issue to retrieve all of them.

If that's the case, your dataset is small enough that you could maintain an index of the keys in another CF.   If it needs to scale further, you can segment the index keys by year, month, etc.
