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

First, Kafka use the background There are a number of issues that can be encountered when using distributed databases and distributed computing clusters: Need to analyze user behavior (pageviews); The user's search keywords are counted to analyze the current trends Some data, storage database waste, direct storage drive efficiency and low These scenarios have one thing in common: Data is generated by the upstream module, upstream module, using the up

1. File System Description File systems are generally divided into two types: system and user. System-level file systems: ext3, ext4, DFS, NTFS, etc ,, I will not introduce the complicated distributed or system-level file system, The architecture design of the Kafka file system is deeply analyzed from the perspective of the high performance of the Kafka architecture. 2.
