Question related Connection Pool settings

Hey 👋

I saw that you used Pool Size = 1 and max overflow = 0

return create_engine(db_conn_string,
echo=debug_mode,
pool_size=1,
max_overflow=0,
pool_recycle=3600,
pool_pre_ping=True,
pool_use_lifo=True)

Was this by intention because of the RDS Proxy?
Could you explain why not a higher Pool Size was used as the RDS Proxy is handling the Connections anyway?

Would love to hear your reasons because I want to run this kind of setup for a productive use case.

Best regards
