Скачать или смотреть Threads vs Coroutines - ParallelMap in Kotlin

When running on the JVM, if we need to run things concurrently we can use Java APIs or Kotlin coroutines. In this episode we implement a parallelMap operation using streams, raw threads, a threadpool with futures, and coroutines. The results may surprise you!

This is part 55 of an exploration of where a Test Driven Development implementation of the Gilded Rose stock control system might take us in Kotlin. You can see the whole series as a playlist

There has been some discussion on Reddit about my use of AtomicReference in the threads implementation. I'm persuaded that any old non-thread-safe holder would do, and would probably be more performant -   / j089h0d  

The next episode (   • Threads vs Coroutines - ParallelMap Perfor...  ) measures the performance of the implementations.
