dataset is a lightweight Python library that simplifies database operations by providing a dict-like interface on top of SQLAlchemy. It automatically creates tables and columns on insert, supports CRUD operations, transactions, and chunked bulk inserts/updates. The library is designed for small to medium-scale data tasks where full ORM overhead is unnecessary. It supports SQLite, PostgreSQL, and MySQL, and is fully type-annotated with mypy strict compliance. The codebase is well-organized into core modules (database, table, types, util, chunked) and has thorough test coverage across all supported backends. While the core abstraction is thin (intentionally), the implementation demonstrates solid engineering discipline with clean APIs, thread safety considerations, and proper handling of SQLAlchemy 2.x quirks.
