instead of all received.Explicitly giving up the control of a task is a bit similar to the way you think about the coroutine. The reactor can look at the scheduler of the coroutine. Reactor is an event loop. We can register events of interest (such as socket-readable/writable) and processors (such as read/write operations) with the reactor ), the reactor calls back our processor when an event occurs. After the processor completes execution, it is equivalent to a coroutine suspension (yield) and

/asynchronousSynchronous/asynchronous is concerned with the mechanism of how messages are notified. The blocking and non-blocking concerns are processing messages. are two completely different sets of concepts. 5. Several common conceptsSelect PollEpoll (Linux) kqueue (FreeBSD)IOCP windowsReactorDispatcher (Dispatcher), Notifer (notifier), when an event arrives, the handler is dispatched with the Dispatcher (dispatcher), which is the Dispatcher to maintain for all registered handler.

tasks (that is, the tasks that receive the output) need to be designed to receive the series of bits or fragments instead of all received. Explicitly giving up the control of a task is a bit similar to the way you think about the coroutine. The reactor can look at the scheduler of the coroutine. Reactor is an event loop. we can register events of interest (such as socket-readable/writable) and processors (such as read/write operations) with the reactor ), the reactor calls back our processor wh

Generally, the I/O multiplexing mechanism relies on an event demultiplexer. The Separator object separates the I/O events from the event source and distributes them to the corresponding Read/write event handler (the event Handler). The developer pre-registers the events and their event handlers (or callback functions) that need to be processed, and the event separator is responsible for passing the request events to the event handler. The two patterns

listening to the server socket,accept new connection, and assigns the established socket to the subreactor. Subreactor is responsible for multiplexing the connected sockets, reading and writing network data, to the business processing function, which is thrown to the worker thread pool to complete. Typically, the number of subreactor is equal to the number of CPUs.2.3 Netty Model2.2 said the reactor three models, then Netty is what kind of? In fact, Netty's threading model is a variant of the r

sources using the synchronization event separator. When the event occurs, the synchronization event separator notifies the reactor manager and finally completes the requested service by the reactor manager scheduling and event handlers associated with the event. structure In the reactor model, there are 5 key players. Descriptor (HANDLE): provided by the operating system to identify each event, such as the socket descriptor, file descriptor, and so on. In Linux, it is represented by an integer.
