High-level concurrency

Coroutines are a standout feature in Kotlin, offering advanced capabilities for managing asynchronous computations. While the standard library provides essential coroutine support, it sometimes falls short in more complex scenarios. The Arrow library fills this gap, offering additional functions and primitives that are useful in Kotlin and other programming languages.

To utilize these features, include the following dependency in your project:

implementation("io.arrow-kt:arrow-fx-coroutines:1.2.1")

Parallel operations

In Chapter 8, Designing for Concurrency, while discussing the Barrier design pattern, we saw the following implementation:

val characters: List<Deferred<FavoriteCharacter>> =
    listOf(
        Me.getFavoriteCharacter(),
        Nana.getFavoriteCharacter(),
        Sebastian.getFavoriteCharacter()
    )
 
println(characters.awaitAll())

Arrow’s parZip function is a prime example of enhancing...
