When should I use Gino instead of SQLAlchemy?

High-performance async PostgreSQL access built on SQLAlchemy Core and the asyncpg driver. Teams who want SQLAlchemy familiarity combined with full async/await support for PostgreSQL. Asyncio services where raw asyncpg performance is needed with a lightweight ORM layer

When should I use SQLAlchemy instead of Gino?

Complex relational database work requiring both high-level ORM and low-level SQL control. Applications that must support multiple database backends from a single codebase. Production data engineering pipelines that need fine-grained control over SQL generation

What are the main weaknesses of Gino?

PostgreSQL only — no support for MySQL, SQLite, or any other database. Limited active development; most teams have moved to SQLAlchemy's native async API. Less documentation and fewer production examples than mainstream ORMs

What are the main weaknesses of SQLAlchemy?

Steep learning curve for the 2.0 API, especially async patterns and type-annotated models. Verbose boilerplate for simple CRUD operations compared to lighter ORMs like Peewee. Bulk insert and update performance requires explicit optimization to match raw SQL

How Python Data Engineers Use These Tools

Gino

Engineers use Gino in async Python services that need PostgreSQL access without the overhead of a full ORM. Because Gino is built on raw asyncpg, it delivers near-native query performance — making it a good fit for high-throughput data ingestion APIs where every millisecond of database latency matters.

SQLAlchemy

SQLAlchemy is the standard Python database toolkit for data engineers. The Core layer is used to construct and execute SQL queries programmatically — building dynamic INSERT/UPDATE statements, managing connection pools in long-running services, and reading query results into pandas DataFrames via `pd.read_sql()`. The ORM layer manages schema-as-code in application codebases.
