Dear friends, I have recently studied kafka and read a lot that kafka may lose messages. I really don't know what scenarios A log system can tolerate the loss of messages. For example, if a real-time log analysis system is used, the log information I see may be incomplete... dear friends, I have recently studied kafka and read a lot that

for lightweight Message Queuing, Kafka uses disk for Message Queuing, so there is no problem with the disk when the message is buffered. It is also recommended to use Kafka for Message Queuing in a production environment. In addition, if the company has Kafka services in operation, Logstash can also be quickly accessed, eliminating the hassle of repetitive const

Kafka concept: Kafka is a high-throughput streaming distributed message system used to process active stream data, such as webpage access views (PM) and logs. It can process big data in real time. It can also be processed offline. Features: 1. High Throughput 2. It is an explicit distributed system that assumes that data producers, brokers, and consumer are scattered across multiple machines. 3. Status info
