hello ppl, I'm writing a columnar storage engine and have a simple version working. however, during table scans or index scans I need to know what fields (columns) were requested by the user. given that this is a columnar db, I only want to fetch the fields the user wants.

can someone pls help me with this question?

thanks
Nishant
