How we deprecated two successful projects and joined forces to create an even more successful one

• fastkafka

  38 33 8.7 Jupyter Notebook

  FastKafka is a powerful and easy-to-use Python library for building asynchronous web services that interact with Kafka topics. Built on top of Pydantic, AIOKafka and AsyncAPI, FastKafka simplifies the process of writing producers and consumers for Kafka topics.

  

After a short discussion, we concluded we were just too spoiled to use low-level libraries that were nothing more than just tiny wrappers around C++ libs and that we could just build our own. So, we shamelessly made one by reusing beloved paradigms from FastAPI and we shamelessly named it FastKafka. The point was to set the expectations right - you get pretty much what you would expect: function decorators for consumers and producers with type hints specifying Pydantic classes for JSON encoding/decoding, automatic message routing to Kafka brokers and documentation generation.

• Propan

  16 466 8.8 Python

  Propan is a powerful and easy-to-use Python framework for building event-driven applications that interact with any MQ Broker

The next step was to figure out what to do next. We posted questions on a few relevant subreddits and got quite a few feature requests, mostly around supporting other protocols, encoding schemas etc. But, we also got a message from a developer of a similar framework Propan that was released at about the same time and was gaining quite a traction in the RabbitMQ community. That developer was Nikita Pastukhov and he made an intriguing proposal: let's join our efforts and create one framework with the best features of both. Both projects were growing at roughly the same speed but targeted different communities. So the potential for double growth was there. After a quick consideration, we realized there was not much to lose and there was a lot to gain. Of course, we would lose absolute control over the project but losing control to the community is the only way for an open-source project to succeed. On the positive side, we would gain a very skilled maintainer who single-handedly created a similar framework all by himself. The frameworks were conceptually very similar so we concluded there would not be much friction of ideas and we should be able to reach consensus on the most important design issues.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• faststream

  13 1,779 9.7 Python

  FastStream is a powerful and easy-to-use Python framework for building asynchronous services interacting with event streams such as Apache Kafka, RabbitMQ, NATS and Redis.

  

After two months of hard work, we presented the newly released FastStream framework at Infobip Shift conference and got featured at ShiftMag. The framework now supports both Apache Kafka and RabbitMQ, but also NATS protocol with the plan to add more protocols in the near future. The overall code is much cleaner and the implementation is streamlined with abstractions covering the common functionality across the protocols. We deprecated both FastKafka and Propan, but promised to fix bugs as long as needed. However, it seems like the community already decided to switch over to gain new functionalities.
