Kafka is a distributed, partitioned, and reproducible message system. It provides common messaging system functions, but has its own unique design. What is this unique design?
First, let's look at several basic terms of the message system:
Kafka sends messagesTopicUnit.

Kafka is a distributed, partitioned, replication-committed publish-Subscribe messaging SystemThe traditional messaging approach consists of two types:
Queued: In a queue, a group of users can read messages from the server and each message is sent to one of them.
Publish-Subscribe: In this model, messages are broadcast to all users.The advantages of Kafka compared to traditional messaging techno
Kafka Cluster Deployment ScenariosZooKeeperFirst step host name to IP address mapping configurationThe zookeeper cluster has two key roles leader and follower. All nodes in the cluster are connected as a whole to the Distributed Application Service cluster each node is interconnected so the mapping of the host to IP address of each node in the configured zookeeper cluster is configured to map information for the other nodes in the cluster.

1. What is Kafka?Kafka is a distributed MQ system developed and open-source by LinkedIn. It is now an incubator project of Apache. On its homepage, Kafka is described as a high-throughput distributed MQ that can distribute messages to different nodes. Kafka is compiled by only 7000 lines of scala. It is understood that

1: You may need to understand the logback log system.
2: You may need a preliminary understanding of Kafka.
3: Before viewing the code, please carefully refer to the business diagram of the system

Problem DescriptionWhen processing with Kafka read messages, consumer reads the data in the Afka queue repeatedly.
problem ReasonKafka's consumer consumption data will first read a batch of message data from broker to process, and then submit offset after processing. and the consumer consumption in our project is low, resulting in the removal of a batch of data in the session.timeout.ms time without processing completed, automatic submission offset fa
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
