Dag Brattli on RxPy

Visit our site to listen to past episodes, support the show, and sign up for our newsletter! Summary Dag Brattli is an engineer with Microsoft and in his spare time he created the ported the Reactive Xtensions framework to Python in the form of the RxPy library. In this episode we had the opportunity to speak with Dag and learn more about what ReactiveX is, why it is useful and how you can use it in your Python programs. It is definitely a very powerful programming patern when manipulating data streams which is becoming increasingly common in modern software architectures.

Interview with Dag Brattli Introductions How did you get introduced to Python? For our listeners who haven’t heard of it before, can you describe what RxPy is and why someone might want to use it? What problem domains are best suited for using the Reactive X approach? What is involved in integrating RxPy into an existing code base? When should we use RxPy over asyncio or asynchronous workers like Celery? What resources or tutorials do you recommend people use when trying to understand how and when to use the Reactive X tools? What in particular about Python lends itself to the ReactiveX pattern, and what features of the language does RxPy leverage in particular in its implementation? In what ways does the Python implementation of the Reactive X framework differ from those of other languages? The project description references the use of LINQ for querying the various data streams that RxPy enables consumption of. I had always heard of LINQ in the context of traditional database queries. What makes LINQ a good choice for stream processing? I mostly hear about ReactiveX in terms of UI design, but the project description seemed to indicate it was much more generally useful. What are some of the less common and more interesting problems that RxPy lends itself to solving?
