Provides PEP-484 typing stubs for SQLAlchemy 1.4, enabling static type checking with mypy and other type checkers.

However, this is a legacy package: it is dormant, explicitly incompatible with SQLAlchemy 2.0, and must be manually uninstalled before upgrading.

Python client for Databricks AI Search, a managed vector and keyword search service on the Databricks platform, supporting endpoint creation, index management, and similarity search queries.

However, the license is restrictive and proprietary—use is only permitted in connection with a Databricks Platform Services agreement.

MongoEngine provides an Object-Document Mapper (ODM) layer on top of PyMongo, letting you define MongoDB documents as Python classes with typed fields and query them using a familiar ORM-like interface.

Install it if you want an ORM-like layer over MongoDB and prefer working with Python classes and typed fields instead of raw dictionaries and queries.
