Python objects normally have a dictionary named __dict__ allocated for handling dynamically assigned attributes. Depending on architecture and Python version, that empty dict may be between 64 and 280 bytes. Seeing as Atom and Datum objects do not need dynamic attribute support and there can be millions of rows in a database, avoiding this allocation with __slots__ can save 100s of MBs of memory per Idl process.
