Question 1

How do I add a new RabbitMQ queue in FastStream with this template?

Accepted Answer

You need to define the queue in your FastStream application code, then manually create it using rabbitmqadmin commands as shown in the README for queue declaration. This involves updating both the code and running Docker exec commands, which can be error-prone.

Question 2

FastAPI-Dishka-FastStream vs Django for building backend apps?

Accepted Answer

This template is better for event-driven microservices with clean architecture, while Django suits monolithic apps with built-in admin and ORM. Django has more batteries included, but this template offers more flexibility for async messaging and dependency injection.

Question 3

Can I use Kafka instead of RabbitMQ with FastStream here?

Accepted Answer

FastStream supports Kafka, but the template is configured for RabbitMQ; switching would require modifying dependencies and FastStream setup, which isn't covered in the README and could involve significant changes.

Question 4

What's the performance impact of Dishka dependency injection?

Accepted Answer

Dishka adds some overhead due to dynamic dependency resolution, but it's minimal in most cases. The trade-off is improved testability and maintainability, as noted in the architecture overview.

Question 5

How to handle database transactions in this clean architecture setup?

Accepted Answer

Use SQLAlchemy sessions managed through Dishka scopes; the template likely includes examples in the codebase, but the README doesn't detail transaction handling, so you might need to refer to external resources or the Habr articles.

Question 6

Is there WebSocket support in FastAPI-Dishka-FastStream?

Accepted Answer

No, the template focuses on HTTP APIs and AMQP messaging; for WebSockets, you'd need to extend FastAPI separately, which isn't integrated with the existing dependency injection or messaging setup.
