Why does GC in languages such as the problem of Java not release memory in real time?Here is Rednaxelafx's answer:1. The most basic pure reference counting method of automatic memory management can be done in real time to release dead objects, but cannot handle the existence of circular references to the release of the

In linux, you can use top or vmstat to view the system's CPU usage. In most cases, the CPU usage is accurate, but in real-time linux systems with high time precision, the CPU usage measured by top may be inaccurate. The following uses the top principle and real-time linux in

sender Report SR. The RTCP datagram contains synchronization information between different media streams, as well as the sent datagram and byte count, the receiving end can estimate the actual data transmission rate based on the information. On the other hand, the receiving end sends the RR report to all known senders. The RTCP datagram contains the maximum serial number of the received datagram, the number of lost datagram, latency jitter, timestamp

Kafka, as shown in the following figure. Unfortunately, Samza only provides at-least once semantics, and exactly once support is also in the plan. Flink provides state operations, similar to Samza. Flink provides two types of status: one is user-defined, and the other is the window state. As shown in the figure, the first state is a custom state, and it does not interact with other states. These states can be partitioned or used with embedded key-value storage states [Documents I and II]. Of co

RTP is defined as a one-to-many transmission, with the purpose of providing time information and implementing stream synchronization

are long Polling, Server Sent Events and Websocket. First, you need to know what Ajax is. This is not introduced. Long pollingpolling Before introducing long Polling, first introduce Polling. Polling is a dumb way to implement the real-time web by periodically sending requests to the server to see if the server's data is changing. If the server data does not change, then return 204 no Content; If there is
