Coroutines: The Async Builder

Coroutine Dispatchers

• Helps you control which thread or thread pool you want the coroutine to run on
• You can switch the thread coroutine when it suspends

Built in dispatchers:

• Dispatchers.Default
  • Shared thread pool
  • Thread count usually matches the number of cores in the CPU
  • Use for CPU tasks (like data transformations)
• Dispatchers.IO
  • Shared thread pool
  • Thread count grows based on the number of coroutines using it
  • Use for IO tasks (like network processing)
• Dispatchers.Main
  • Single main UI thread
  • Used in Javascript, Swing, Android etc
