The philosophy of Erlang and StreamBase align quite well. Quoting Mike Williams, one of the three inventors of Erlang:
- Find the right methods—Design by Prototyping
- It is not good enough to have ideas, you must also be able to implement them and know they work
- Make mistakes on a small scale, not in a production project
These philosophies of rapid development also apply to the way we've designed StreamBase; additionally, our customers also demand that much less technical users participate in the rapid implementation of ideas. StreamBase has a visual development approach that allows less technical, more "business" users - with mathematics, analytics, and business domain expertise - use the same tools as professional software developers.
What if we could add Erlang developers to that party? Event-driven, visual development, coupled with the power and rapid development of Erlang?
Well you can. Darach Ennis (@darachennis) shows us how in his recent presentation at Erlang UG in London.
StreamBase has a graphical, compiler-oriented programming language, targeted at serious developers, that can also be used by the less technical. Erlang programmers, and the Erjang folks with whom we share a virtual machine, do their thing in Erlang, and that code becomes a graphical "operator" on the StreamBase Studio pallet. In Darach's example he's used Erlang to implement a MACD analytic, and integrate that into a StreamBase-based trading system so it operates in the event-driven CEP application.
The combination of StreamBase and Erlang combines the best of both worlds: StreamBase for rapid, graphical development to develop low latency applications that process 100's of thousands of events a second. Combining "how," "why," and "under what conditions," real time streams are matched and processed. StreamBase allows business analysts, actuaries, quantitative contributors and developers to share a common language. An event-driven integration whiteboard, if you will, that compiles to efficient optimized native binary code. Add Erlang for development of analytics like MACD and you have a powerful combination.
Erlang support will be contributed soon to the StreamBase Component Exchange (SBX), our public "app exchange" for CEP integrations, applications, frameworks, and sample code. You'll already find support for Java, C++, R, Matlab, python, .NET. If you want to plug in some cool analytics written in C++, just do it. You want to exploit Basho's Riak? Sure, plug it in.
As a result, StreamBase allows developers control over how they exploit the facilities at their disposal. Use our graphical DSL for flow oriented algorithms and real time low latency high frequency data management. It's high performance from a human productivity and systemic perspective.
