Learning Concurrency in Kotlin

Leveraged

Creating and managing threads is one of the difficult parts of writing concurrent code in many languages. As seen before, it's important to know when to create a thread, and almost as important to know how many threads are optimal. It's also important to have threads dedicated to I/O operations, while also having threads to tackle CPU-bound operations. And communicating/syncing threads is a challenge in itself.

Kotlin has high-level functions and primitives that make it easier to implement concurrent code:

• To create a thread it's enough to call newSingleThreadContext(), a function that only takes the name of the thread. Once created, that thread can be used to run as many coroutines as needed.
• Creating a pool of threads is as easy, ...
