cicuit breakers

Mike,

you talk a lot about circuit breakers and it sounds like a very useful pattern, indeed. Are there any existing implementations? A cursory google search didn’t return any results. Perhaps, the pattern is also known under a different name?

Thanks
Dmitry

Dmitry,

The name “Circuit Breaker” is one that I coined, so I would not expect to find many references to it (yet.)

The existing implementations I’ve used are proprietary and are not something I can share. One of the common requests I’ve heard, however, is for some sample code. I am considering taking this on as an open source project.

What language would be most useful? I’m torn between doing an implementation in Ruby, where I might be able to use metaprogramming techniques to make using a circuit break a one-line declarative statement, versus doing it in Java, which has much more widespread applicability in the enterprise.

Cheers,

Thanks for the reply, Mike. I was just wondering if there was anythgin out there before starting coding on my own. An open source project would be cool, though, especially if it’s in Java, then I could even try to contribute. If it ends up being in Ruby, not a problem either, I can always rewrite it in Java myself.

thanks

Hello, it would be better to see it in Java, since we can use that code to write in other languages as well, since a oneliner in ruby wouldn’t be usefull to extend in other languages.
