Given a Future returned by the code you are testing, you need not block until the Future completes before performing assertions against its value. The Scala Async library In the final section of this chapter, we turn to the Scala Async library. You should understand that the Scala Async library does not add anything … - Selection from Learning Concurrent Programming in Scala [Book] Async database access with PostgreSQL, Play, Scala and Heroku Last year I felt I wanted to contribute in some way to the Scala community. Since I didn’t think I was smart enought to work on the main libraries or compiler, I started to look for something that I could build and would benefit me and the community in general. Note how complicated the chaining of continuations can gets, and the same happens in Scala, but there is a feature that C# has that kills Scala in this aspect. The last code can be rewritten in the following way using the async/await pattern from C# foreachPartitionAsync(scala.Function1 f) -> Applies a function f to each partition of this RDD. takeAsync(int num) -> Returns a future for retrieving the first num elements of the RDD. Now let us see what happen when we use async actions.

In async application it gets ugly(er): In async application one request is likely to be handled by multiple threads. I have read this in https://github.com/scala/async. Theoretically this code is asynchronous (non-blocking), but it's not parallelized: def slowCalcFuture: Future [Int] = def combined: Future [Int] = async { await (slowCalcFuture) + await (slowCalcFuture) } val x: Int = Await.result (combined, 10.seconds) whereas this other one is parallelized: * the "async" keyword tells the compiler to look for any "await" areas and make them non-blocking * in our example, we wish to fetch the contents of 2 files via http in a non-blocking manner * @return a string wrapped in a Future result 2018-07-20 scala-async . A DSL to enable a direct style of programming with when composing values wrapped in Scala Futures.

Scala Futures provide mechanisms for chaining together async computations, often in the form of monadic transformations such as map and flatMap. These transformation methods produce async tasks to be run on the provided execution context.

Like Elm and Haskell, Scala also has a function that can chain async operations (theirs is called flatMap ).

The backends can integrate with a variety of Scala stacks, providing both synchronous and asynchronous, procedural and functional interfaces.

Occasionally, someone will ask about support for some kind of implicit “context” that will flow with async code. The most common use case is for logging, where you can maintain a stack of logical operations so every time you log you capture (and log) the state of that stack (e.g., CorrelationManager for TraceSource, or the Nested Diagnostic Context for log4net). Asynchronous communication. Actors are reactive and message driven.

Asynchronous communication. Actors are reactive and message driven. An Actor doesn’t do anything until it receives a message. Actors communicate using asynchronous messages.

Har tidigare lekt en del med Scala, LINQ och motsvarande i Scala är detta område är async+await i C#. async/await gör det väldigt enkelt att  Det tillhandahålls av funktionen async och klassen future. Grundfunktion ThoughtWorks verkar vidare tro på Scala lite mer än jag gör.
