Many of the company's platforms generate a large number of logs per day (typically streaming data, such as search engine PV, queries, etc.), and processing these logs requires a specific logging system, in general, these systems need to have the following characteristics:

Kafka is a distributed publish-subscribe message system, simply a message queue, the advantage is that the data is persisted to disk (the focus of this article is not to introduce Kafka, do not say more).
