Production-ready async SQLAlchemy 2.0+ patterns for FastAPI: session management, connection pooling, Alembic migrations, relationship loading strategies, and qu
Provides a compact, opinionated collection of patterns and templates to implement production-ready async SQLAlchemy (2.0+) in FastAPI projects. It codifies engine and async session setup, dependency patterns for DB sessions, base model mixins (timestamps, soft delete), relationship loading strategies to avoid N+1 queries, transaction and nested transaction patterns, bulk operations, streaming large query results, and Alembic migration templates. The package includes scripts and templates to bootstrap migrations and common examples to illustrate correct usage.
Use this skill when building or migrating a FastAPI application to async SQLAlchemy 2.0+, when you need reliable session management, when tuning connection pools for production, when generating and reviewing Alembic migrations, or when addressing performance issues like N+1 queries or heavy bulk operations. It is also useful during onboarding for teams that want standard DB patterns.
Best suited for coding assistants that can read and apply repository patterns (Claude Code, Copilot-like coding tools) and for maintainers working with Python/SQLAlchemy stacks.
