The Reactor and Proactor design patterns
When using event handling applications, we can follow two approaches to designing the concurrent solution: the Reactor and Proactor design patterns.
These patterns describe the mechanisms followed to process events, indicating how these are initiated, received, demultiplexed, and dispatched. As the system collects and queues the I/O events coming from different resources, demultiplexing these events means separating them to be dispatched to their correct handlers.
The Reactor pattern demultiplexes and dispatches synchronously and serially service requests. It usually follows a non-blocking synchronous I/O strategy, returning the result if the operation can be executed, or an error if the system has no resources to complete the operation.
On the other hand, the Proactor pattern allows demultiplexing and dispatching service requests in an efficient asynchronous way by immediately returning the control to the caller, indicating that the...
