SQLAlchemy Archives - Python Lore

Mastering SQLAlchemy involves managing sessions effectively and executing optimized queries. Utilize sessions as transactional scopes, create short-lived sessions per request, and implement proper lifecycle management. Write expressive queries with filters and joins, and ensure safe raw SQL execution. Understand flushing to maintain in-memory state synchronization.
