Concurrent implementation of millions of servers based on EPOLL-based reactor
1. In what scenarios should level trigger or edge trigger be used? When the amount of data is relatively small and the performance is relatively high, we generally use edge triggering. (How do we divide the size of the data? When the buffer cannot be read at one time, it is large data, and if […]

websocket demo based on stomp protocol
What is stomp STOMP (Simple (or Streaming) Text Orientated Messaging Protocol) is a simple text protocol that defines the format for communication between clients and message brokers. It is an interoperable protocol because many different message brokers and clients implement it. STOMP provides a reliable, asynchronous messaging model that is suitable for communicating between heterogeneous […]
Irregular use of the thread exception caused by CountDownLatch to wait for timeout
Quote: The concept of CountDownLatch: Allow one or more threads to wait for other threads to complete operations. The constructor allows to receive an int value as the initial number of threads, which can also be considered as the last few numbers. After the thread execution is completed, the count value in the construction is […]
