The provided code appears to be functioning correctly without apparent issues. However, it can be optimized slightly:

         }

Optimizations Made:

1. Default Value Handling: Added a check using an if statement to set the MAX_OVERFLOW value to None if it is not found in the configuration, preventing unnecessary conversion attempts (int(None)).

This change ensures that any missing or empty DB_MAX_OVERFLOW configuration values will gracefully handle this scenario without raising exceptions when converting them to integers.
