Introduced
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

To demonstrate the effect of the cluster, a virtual machine (window 7) is prepared, and a single IP multi-node zookeeper cluster is built in the virtual machine (the same is true for multiple IP nodes), and Kafka is installed in both native (Win 7) and virtual machines.Pre-preparation instructions:1. 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.

Kafka FoundationKafka has four core APIs:
The application uses Producer API a publishing message to 1 or more topic (themes).
The application uses Consumer API to subscribe to one or more topic and process the resulting message.
Applications use Streams API acting as a stream processor, consuming input streams from 1 or more topic, and producing an output stream to 1 or more output topic, effectively swapping input streams to the outp
Kafka is a distributed publish-subscribe messaging system. It was originally developed by LinkedIn and later became part of the Apache project.

It is primarily used to process active streaming data.In big Data system, often encounter a problem, the whole big data is composed of each subsystem, the data needs in each subsyst

Data typically includes user activity, event logins, page access, clicks, social networking activities such as like, share, and comment, actionsand system metrics (due to high throughput (millions of messages per second), typically handled by logging Legacy Log Aggregation solutions-for offline analysis Eg.hadoop)Very limited to building real-time processing systems.

Each partition is a commit log and has an offset. The topic in the queue can be configured with an expiration time,
The consumer controls the position of the read Offset,consumer between the non-affected. Partitions are distributed, all requests are handled by leader, and if the number of replicas is configured, there is a corresponding follwer.
Consumer group: Message Queuing and broadcast are implemented.
Topic will be sent to one of the consumer instances of each consumer group.
