Chapter 2 distributed system mode Broker (agent) and Chapter 4 broker Many complex software systems run on multiple processors or distributed computers. Software is distributed across multiple computers for a variety of reasons, such: A Distributed System can utilize the computing power of multiple CPUs or a group of low-cost computers. A software may only be available on a specific computer. For securi

Kafka is a distributed MQ system developed by LinkedIn and open source, and is now an Apache incubation project. On its homepage describes Kafka as a high-throughput distributed (capable of spreading messages across different nodes) MQ. In this blog post, the author simply mentions the reasons for developing Kafka without choosing an existing MQ system. Two reaso

Persistent messages to disks can be used for batch consumption, such as ETL and real-time applications. Data can be persisted to the hard disk and replicated to prevent data loss. Distributed System, easy to scale out. All producer, broker, and consumer are distributed. Machines can be expanded without downtime. The status of the message

Most of them use a "push" model in which the broker forwards data to consumers. at LinkedIn, we find the "pull" model more suitable for our applications since each consumer can retrieve the messages at the maximum rate it can sustain andAvoid being floodedBy messages pushed faster than it can handle. Why should we use pull instead of push? consumer's hunger is only known by consumer, so it is reasonable for the
