[Question] A repository for every entity?

[PrasannaVenkadesh]

My question is regarding the repository pattern.

In your example, you have only created a SQLAlchemyRepository for storing and retrieving Batch entities, but not Orders or Products. This lead me to confusion, What if, I want to query for all Orders or all Products?

Do we need to define SQLAlchemyRepository class for each entity? I don't think so, but at the same time, I cannot also understand how would I query for all orders and products.
