简介: Akka is a concurrency framework built around the notion of actors and composable futures, Akka was inspired by Erlang which was built from the ground up around the Actor paradigm. It would usually be used to replace blocking locks such as synchronized, read write locks and the like with...
Actors Only Process One Message at A Time Take a number and stand in line, pal! Ok, well it’s not really like that. One of the guarantees actors in Akka.NET make is that an actor’s context and internal state are always thread-safe when processing a messages. The reasons this is ...

In that statement, Mr. Armstrong’s “processes” are equivalent to Akka actors, so the same statement can be made: “Actors share no data with other actors, and because of this we can easily distribute Akka programs over multicores or networks.” As you’ll see in the lessons to come,...
Kafka enable in-memory microservices (actors, Akka, Baratine.io, QBit, reactors, reactive, Vert.x, RxJava, Spring Reactor) Kafka allows you to build real-time streaming applications that react to streams to do real-time data analytics, transform, react, aggregate, join real-time data flows ...
Unlike specialized actor frameworks such as Erlang, Akka, and Orleans, Ray integrates the actor framework directly into programming languages. In addition, Ray’s distributed objects support data sharing across actors. Workflows When most people talk about workflows, they talk about UI or script-drive...
T here are days in New York—surprisingly many of them, all things considered—when it’s almost possible to forget that we are living in an age of terror. And then there are days, like last Thursday with its headlines out of London, when that gri [...]
