Netflix: Solving Big Problems with Reactive Extensions (Rx)

Netflix: Solving Big Problems with Reactive Extensions (Rx) by Claudio Caldato.

From the post:

More good news for Reactive Extensions (Rx).

Just yesterday, we told you about improvements we’ve made to two Microsoft Open Technologies, Inc., releases: Rx and ActorFx, and mentioned that Netflix was already reaping the benefits of Rx.

To top it off, on the same day, Netflix announced a Java implementation of Rx, RxJava, was now available in the Netflix Github repository. That’s great news to hear, especially given how Ben Christensen and Jafar Husain outlined on the Netflix Tech blog that their goal is to “stay close to the original Rx.NET implementation” and that “all contracts of Rx should be the same.”

Netflix also contributed a great series of interactive exercises for learning Microsoft’s Reactive Extensions (Rx) Library for JavaScript as well as some fundamentals for functional programming techniques.

Rx as implemented in RxJava is part of the solution Netflix has developed for improving the processing of 2+ billion incoming requests a day for millions of customers around the world.

Do you have 2+ billion requests coming into your topic map every day?

Assuming the lesser includes the greater, you may want to take a look at Rx or RxJava.

Be sure to visit the interactive exercises!

Rx 2.1 and ActorFx V0.2

Rx 2.1 and ActorFx V0.2 by Claudio Caldato.

From the post:

Today Microsoft Open Technologies, Inc., is releasing updates to improve two cloud programming projects from our MS Open Tech Hub: Rx and ActorFx .

Reactive Extension (Rx) is a programming model that allows developers to use a common interface for writing applications that interact with diverse data sources, like stock quotes, Tweets, computer events, and Web service requests. Since Rx was open-sourced by MS Open Tech in November, 2012, it has become an important under-the-hood component of several high-availability multi-platform applications, including NetFlix and GitHub.

Rx 2.1 is available now via the Rx CodePlex project and includes support for Windows Phone 8, various bug fixes and contributions from the community.

ActorFx provides a non-prescriptive, language-independent model of dynamic distributed objects for highly available data structures and other logical entities via a standardized framework and infrastructure. ActorFx is based on the idea of the mathematical Actor Model, which was adapted by Microsoft’s Eric Meijer for cloud data management.

ActorFx V0.2 is available now at the CodePlex ActorFx project, originally open sourced in December 2012. The most significant new feature in our early prototype is Actor-to-Actor communication.

The Hub engineering program has been a great place to collaborate on these projects, as these assignments give us the agility and resources to work with the community. Stay tuned for more updates soon!

With each step towards better access to diverse data sources, the semantic impedance between data systems becomes more evident.

To say nothing of the semantics of the data you obtain.

The question to ask is:

Will new data makes sense when combined with data I already have?

If you don’t know or if the answer is no, you may need a topic map.
