How does Kotlin handle scalability bottlenecks in coroutine-heavy systems?

Bottlenecks occur due to blocking calls, excessive context switching, and unbounded coroutine creation.

Although coroutines are lightweight, misuse can still cause scalability issues. Launching too many coroutines without control leads to scheduler overload. Blocking calls inside coroutines defeat their purpose. Excessive context switching between dispatchers adds overhead. Proper structured concurrency and batching strategies are required for scalability.
