Kafka is a distributed, partitioned, replicable messaging system. It provides the functionality of a common messaging system, but has its own unique design. What does this unique design look like?
Let's first look at a few basic messaging system terms:
Kafka the message to topic as a unit.• The program that will release the message to Kafka topic
Introduction to Kafka
Kafka is a high-throughput distributed Message Queue with high performance, persistence, multi-copy backup, and horizontal scaling capabilities. It is usually used on big data and stream processing platforms. Message Queues all have the producer/consumer concept. The producer writes messages to the queue, while the consumer obtains messages from the queue. It is generally used for deco
Kafka is a distributed streaming platform, what exactly does it mean.
The streaming platform has the following three main functions:☆ Publish and subscribe stream records, similar to Message Queuing or enterprise-level messaging systems.☆ You store stream records in a fault-tolerant manner.☆ Timely processing when the flow record is generated.
Kafka is used in two major categories of applications:☆ Establis

Three zookeeper servers, the local installation of one as Server1, virtual machine installation two (single IP)2. Three

What's Kafka?
Kafka, originally developed by LinkedIn, is a distributed, partitioned, multiple-copy, multiple-subscriber, zookeeper-coordinated distributed logging system (also known as an MQ system), commonly used for Web/nginx logs, access logs, messaging services, and so on, LinkedIn contributed to the Apache Foundation in 2010 and became the top open source project.
