Description
- this is currently done using sql_io.put_table()'s col_defaults parameter, which only supports constant values
- the col_defaults mechanism should be expanded to be able to use any input column, or any value which is generatable from input columns
- any value generated for a col_default should be cached permanently in the input table for reuse by other col_defaults, including col_defaults for future imports
- if the input table is a view, the view must first be materialized for this to work
