Learning Akka (Video 39)

This video tutorial explores the throttling messages pattern, a technique used to control the rate at which messages are sent in applications, particularly when interacting with external web services that have request limitations. The tutorial covers the pattern's skeleton, including its FSM actor with idle and active states, and provides a practical implementation example. It concludes with a summary and references to further resources.

What is the purpose of the throttling message pattern in an application?

Describe how the throttling mechanism works when the number of messages exceeds the specified limit.

What are the two states of the FSM actor in the time-based throttling pattern?

Explain the transition from the idle state to the active state in the throttling pattern.

What should be done when a queue message arrives and the target is set in the active state?
