Hi,

First of all, really interesting software. I'm trying to do with easy-etl + dataset, on the 2 db, i need to append timestamp (must be created the new column at the end on 2 db and every row must have timestamp value). Thank you very much

Regards

We usually do this on the application level, so I'm curious what you think the cleanest way of implementing this would be. Perhaps we should build in support for blinker that allows you to add a callback function into the insert code and set your column names there.

Maybe allow create_column() to accept a callback in default= returning the default value.
