FastStream simplifies the process of writing producers and consumers for message queues, handling all the parsing, networking and documentation generation automatically.
Here's a look at the core features that make FastStream a go-to framework for modern, data-centric microservices:
- Multiple Brokers: FastStream provides a unified API to work across multiple message brokers (Kafka, RabbitMQ support)
- Pydantic Validation: Leverage Pydantic's validation capabilities to serialize and validates incoming messages
- Automatic Docs: Stay ahead with automatic AsyncAPI documentation
- Intuitive: Full-typed editor support makes your development experience smooth, catching errors before they reach runtime
- Powerful Dependency Injection System: Manage your service dependencies efficiently with FastStream's built-in DI system
- Testable: Supports in-memory tests, making your CI/CD pipeline faster and more reliable
- Extendable: Use extensions for lifespans, custom serialization and middlewares
- Integrations: FastStream is fully compatible with any HTTP framework you want (FastAPI especially)
How FastStream benefits from the usage of asyncio? Is it able to concurrently process another message while a message awaits for I/O operation? Is this the default behavior, or does it requires some parameter tweak? Does it behaves differently when using FastStream as a FastAPI plugin/addon? I've being using Propan for a while, and planning to move to FastStream asap. Great tool btw, thank you for all your combined effort now. Congrats!
Not natively, but you have a tools to run multiple brokers manually (run them together at lifespan hooks). In the nearest future we will add this feature at the framework core.
Looks great!
Could FastStream be suitable choice for running ML inferences with improved memory management and congestion control compared to REST APIs?
Actually, serving ML inferences was the initial motivation for building the library. We couldn’t find anything similar to FastAPI for Apache Kafka and then we decided to build one.
