πŸ‘‰ Reaqtor: Reliable Rx at Scale for High-performance Event Processing
The Reactive Extensions for .NET (Rx) is one of the most influential technologies to have emerged from the .NET ecosystem. (Its influence on other platforms has been so pervasive that its origins in .NET are sometimes forgotten.) The team that created Rx did not rest on their laurels: they used Rx as the basis for developing a distributed, reliable, and extremely scalable event processing service. Reactor, as it was then called, has been integral to some of Microsoft's most widely used services for many years, but although Microsoft has talked in public about it a few times, it has never been available for use outside of Microsoftβ€”until now. On May 18th 2021, Bart de Smet, made Reaqtor (its new name) open source, as a .NET-Foundation-sponsored project.

This talk will explain what makes Reaqtor different from other high-scale event processing systems. It will also show some of the foundational components that have been released as part of this, most notably 'Bonsai', a mechanism for serializing computations based on .NET's expression tree system, and which is central to how Reaqtor works.

πŸ‘¨β€πŸ’»Carmel Eve
Carmel is a software engineer, LinkedIn Learning instructor and STEM ambassador.

Over the past four years she has been focused on delivering cloud-first solutions to a variety of problems. These have ranged from highly-performant serverless architectures, to web applications, to reporting and insight pipelines and data analytics engines.

In her time at endjin, she has written many blog posts covering a huge range of topics, including deconstructing Rx operators and mental well-being and managing remote working.

Carmel's first LinkedIn Learning course on how to prepare for the Az-204 exam - developing solutions for Microsoft Azure - is due for release next month. And over the last couple of years she has also spoken at NDC, APISpecs and SQLBits. These talks covered a range of topics, from reactive big-data processing to secure Azure architectures.

She is also passionate about diversity and inclusivity in tech. She is a STEM ambassador in her local community and is taking part in a local mentorship scheme. Through this work she hopes to be a part of positive change in the industry.

Carmel won "Apprentice Engineer of the Year" at the Computing Rising Star Awards 2019.
