DB Design Question. (BLOB)

When designing the db, I want to insert the Python code in blob type. I have a lot on my mind. I'm worried if this is efficient. Is it right to put it in considering translation and integrity? Or is it more efficient to put the path of the Python code file into the database?

On the backup side, it would be better to lighten the database by inserting only the path to the Python code file.

I wonder what kind of thoughts you have.

For your information, the amount of Python code is at least 300 lines.
