Eugene Tolmachev & Justin Sacks on events for distributed real-time computation
Details
Eugene & Justin kick up a storm in Mississauga with an event on events.
Abstract:
Events - there are probably a lot more of them in your domain than you might think, but the event-driven approach to designing systems is not an obvious choice for most. It was called "programming without the stack" and it can be a frightening proposition.
However, modeling interactions with events offers several essential benefits: high availability and scalability, as well as low coupling. Another challenge is that event streaming and guaranteed processing put conflicting pressures on the design choices - the former requires low latency and the latter tends to increase it due to IO constraints of persistent storage.

Fortunately writing a few lines of F# and letting Apache Storm (https://storm.apache.org/) take care of the rest makes these benefits easy to achieve.

The power of FsStorm will be demonstrated with a practical example called Word Count (https://github.com/FsStorm/FsStorm.WordCount).

Apache Storm (https://storm.apache.org/) is a distributed computation framework open-sourced after being acquired by Twitter. It uses custom created "spouts" and "bolts" to define information sources and manipulations to allow batch, distributed processing of streaming data. It's like a continuously running map-reduce process.
FsStorm (https://fsstorm.github.io/FsStorm/)is a library for implementation of Apache Storm components, definition of topologies in an F# domain specific language (DSL), and submission via F# scripts for execution.
Speaker bio:
Eugene is a software craftsman and intentional polyglot with over 20 years of experience in a variety of roles and industries. As an architect at Prolucid he works on research and development of IoT technologies and maintains FsStorm - an open-source library for implementing Storm topologies (https://storm.apache.org/documentation/Understanding-the-parallelism-of-a-Storm-topology.html) in F#. Read his blog: thoughtspam (https://thoughtspam.wordpress.com/).
Justin has over 8 years of software development experience in several languages and industries and has only recently been enjoying the efficacy of F#. His role at Prolucid has involved work in the energy sector creating a communications framework for Smart Grid applications, as well as in the agricultural sector implementing a cloud-based grain management system. His ultimate goal is to use his software skills to enable the widespread adoption of distributed and renewable energy sources. ]
