Millised on erinevused Dispatchers.IO ja Dispatchers.Default vahel Kotlin korutinites?

Dispatchers.IO and Dispatchers.Default are the standard dispatchers of Kotlin coroutines, which control on which threads the coroutines are executed.

• Dispatchers.Default is designed for CPU-intensive tasks, such as calculations, data processing, etc. It uses a thread pool whose size is usually equal to the number of available processor cores.

• Dispatchers.IO is optimized for input/output operations (reading/writing files, network requests, working with databases). It uses a scalable thread pool that can grow dynamically to avoid blocking coroutines during long input/output operations.

Example of usage:

// CPU-intensive task
withContext(Dispatchers.Default) {
    // complex calculations
}

// Input/output operation
withContext(Dispatchers.IO) {
    // reading a file or network request
}

Thus, the choice of dispatcher depends on the nature of the task: for calculations — Default, for input/output — IO.
