This blog post discusses the importance of asynchronous architecture and how Kotlin coroutines can be combined with Ably, a messaging infrastructure provider, to develop a multiplayer game room SDK. The author explains that asynchronous programming is essential for various tasks such as running expensive computations in the background, reading from a disk without blocking the user interface, or retrieving data from a network resource. They also highlight how Ably's publish/subscribe pattern can be used to deliver data at low latency and how coroutines simplify internal messaging workflows. The post provides examples of transforming callback-based functions into suspending functions and translating Ably models to domain models, demonstrating the compatibility between Ably and Kotlin coroutines in building realtime applications.
