I have a Background Service that performs some tasks and jobs on a long running thread. For simplicity, We'll consider this as a scheduler that makes an async SQL call and repeats. Now I use AsyncL...

As Stephen Toub explained in this post, when you submit a message to an ActionBlock, you can ExecutionContext.Capture before calling ActionBlock.Post, pass a DTO holding both message and ExecutionC...

I am trying to understand asynchronous models in C++. I am investigating 4 libraries that purport to deal with asynchronous I/O: liburing (C version, C++ version): provides an interface for io_uri...

When the click event is fired from the mouse, it behaves as expected: First the listener 1 is pushed into the stack where it queues promise 1 in Microtask Queue(or Job Queue). When listener 1 is po...

I'm trying to test the ExecutionContext behaviour in a play app, and found that I'm not able to achieve any degree of parallelism when I'm using the default dispatcher either by calling as.di...

I'm having difficulty understanding the mechanics behind ExecutionContext. From what I've read online, context-sensitive items such as security (Thread Principal), culture, etc, should flow across...

Consider the following code: private static async Task Main(string[] args) { await SetValueInAsyncMethod(); PrintValue(); await SetValueInNonAsyncMethod(); PrintValue(); } private static rea...

I have some synchronous calls in my Scala code. I've wrapped them in a blocking() context and then in a Future: Future(blocking(syncCall())), but I don't know which type of ExecutionContext to use....

When a thread dies due to an exception, what happens to this thread? If it is inside a thread pool, does it spawn a new thread? I'm interested in what happens in scala ExecutionContext, but since a...

I have a simple question on using the fork join thread pool. Here is a short example of what I'm using: executor = "fork-join-executor" # Configuration for the fork join pool fork-join-executor...

I am just getting started with Akka Stream and I am trying to figure something out: Currently, in my flows I am using mapAsync() to integrate with my rest services, as recommended here. I have be...

For some reason I can't wrap my head around implementing this. I've got an application running with Play that calls out to Elastic Search. As part of my design, my service uses the Java API wrapped...

I am following the akka-in-action tutorial and in chapter 2, there is a class (https://github.com/RayRoestenburg/akka-in-action/blob/master/chapter2/src/main/scala/com/goticks/RestInterface.scala):...

A new execution context is created for each function in JavaScript. How many execution contexts are present in memory when the following code is run? Note that function Bar is not invoked. functi...

I'm having problems with my Playframework application not being responsive from time to time and I would like to detect this at runtime + log information on what is currently running on the exhaust...

When I make a future, or apply methods like onSuccess and map, I can specify ExecutionContext for them. For example, val f = future { // code } executionContext f.map(someFunction)(executionCon...

I have a WCF service which has its Thread.CurrentPrincipal set in the ServiceConfiguration.ClaimsAuthorizationManager. When I implement the service asynchronously like this: public IAsyncResult ...

I've read a few tutorials on how to deal with concurrency in Play and found some examples: Asynchronous Job import scala.concurrent.{ExecutionContext, future} def sendEmailAsync(from: String, to...

Would using Thread.CurrentPrincipal's claims in a referenced library that uses ConfigureAwait(false) pose any problems or will the flowing of ExecutionContext's logical call context take care of me...

I'm creating an async library using Scala 2.10 futures. The constructor for the library takes a sequence of user-defined objects that implement a certain trait, and then a method on the library cla...

I am trying to discover how the ExecutionContext actually works in version 4.0 and above of the .NET Framework. The documentation says that the managed principle, synchronization, locale and user c...
