Introduction Kafka is a distributed, partitioned, replicable messaging system. It provides the functionality of a common messaging system, but has its own unique design.What is this unique design like? First, let's look at a few basic messaging system terminology: Kafka the message in the topic Unit. The program that publishes the message to Kafka to

If you want to use code to run Kafka application, then you'd better first give the official website example in a single-machine environment and distributed environment to run, and then gradually replace the original consumer, producer and broker to write their own code. So before reading this article you need to have the following prerequisites:1. Simple understanding of the Kafka function, understanding th

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

Apache Kafka is a distributed streaming platform. What exactly does that mean?We think of the three key capabilities of the streaming platform:1. Let you publish a subscription to the data stream. So he's a lot like a message queue and an enterprise-class messaging system.2. Lets you store data streams in a high-fault-tolerant manner.3. Let your data flow out of the current processing them.What is Kafka goo

Install Kafka on CentOS 7Introduction Kafka is a high-throughput distributed publish/subscribe message system. It can replace traditional message queues for decoupling Data Processing and caching unprocessed messages. It also has a higher throughput, it supports partitioning, multiple copies, and redundancy, and is widely used in large-scale message data processing applications.
