AWS glue get columns by name

Question

I have 2 types of csv files - one containing 10 columns and one containing 50 columns. The 10 columns from the first file type appear also in the second file type and I want to crawl only these 10 columns from both of the file types. In the future, I might have different file types containing these 10 columns and some additional columns. How can I get the 10 columns by the column name? The column name will remain the same always.
