What is future in scala
3 Sep 2019 Creating Futures. The basic building block is scala.concurrent.Future , which we have imported under as simply Future : @ Future The missing utils for working with Scala Futures. Futiles contains one addition to that concept which basically does the same, but applies the function I'll talk about Akka/Scala, because I'm not familiar with Gpars nor with Akka/Java. In Scala 2.10, which includes the relevant part of Akka in the standard 15 Jul 2016 Scala's futures are quite nice to use in comparison to similar devices in Future , where it will run asynchronously on who-knows-what-thread; A really useful technique when working with Future is what I call Async Continuation Passing Style (ACPS), which was introduced to me by Marius Eriksen (@
18 Apr 2017 Scala allows us to define callback functions, which execute upon a Future's success or failure. In the meantime, the thread that created the Future
In the previous example, we showed how you can make use of flatMap() method to chain multiple futures. Scala provides a syntactic sugar for flatMap() method which is called the for comprehension. To this end, let's re-write the flatMap() example above and use for comprehension to chain and sequence futures. A Future gives you a simple way to run an algorithm concurrently. A future starts running concurrently when you create it and returns a result at some point, well, in the future. In Scala, it’s said that a future returns “eventually.” The following examples show a variety of ways to create futures and work with their eventual results. Back to top What is a Future? A Future is essentially a placeholder object that is created for a result that does not yet exist. Scala Futures are asynchronous and non The future of Scala is linked to the future of the frameworks that use it. Spark, Akka, Kafka or Play. A significan number of developer dive into the language with the need to leverage these frameworks more effectively. For better or worse, Scala is perceived as a language for large scale data processing.

A Future is a placeholder object for a value that may not yet exist. Generally, the value of the Future is supplied concurrently and can subsequently be used.
1 Answer 1. As soon as you define a Future {} it is started right away, which means when you define f1 and f2 as two futures f1 starts executing and then f2 starts right way. So any of those can finish first. See REPL example below when you define Future as val it is executed right away.
