Abstract—Channels in Kotlin are a feature that allows synchronization and communication between independently running tasks. They are quite versatile and can be used in a variety of applications. However, the use of Channels requires certain amount of care due to its complex nature. At the same time, Kotlin also offers Flows which are simpler to use. Flows however, cannot be used in all cases that are supported by Channels. Especially when dealing with hot data producers, Channels are the better option. In this paper we look at Channels, the use cases they support and caveats associated with their use. We also compare Channels with Flows and discuss scenarios each one is better suited to.
Keywords—synchronization, concurrency, producer-consumer pattern, cold and hot data sources
