sqlalchemy-2-async

Modern async database patterns with SQLAlchemy 2.0, AsyncSession, and FastAPI integration.

| Session scope | One AsyncSession per task/request | SQLAlchemy docs: "AsyncSession per task" | | Scoped sessions | Avoid for async | Maintainers discourage for async code | | Lazy loading | Use lazy="raise" + explicit loads | Prevents accidental N+1 in async | | Eager loading | selectinload for collections | Better than joinedload for async |

| expireoncommit | Set to False | Prevents lazy load errors after commit | | Connection pool | poolpreping=True | Validates connections before use | | Bulk inserts | Chunk 1000-10000 rows | Memory management for large inserts |
