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

When you write Kafka producer, the Keyedmessage object is generated.KeyedmessageHere the key value can be null, in this case, Kafka will send this message to which partition? According to Kafka's official documentation, the default partition class randomly picks a partition: The third property "Partitioner.class" defines, what class-to-determine which Pa

First, prefaceIn a multi-person collaborative project, in addition to good code specifications, the complete API documentation is also very important. Through the documentation we quickly understand the actual interface of each module of the system, its usage scenarios, use examples to reduce communication costs to a certain extent, and reduce the risk of loss of knowledge in later maintenance.For. Net, we

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 publish-subscribe messaging system, which is simply a message queue, and the benefit is that the data is persisted to disk (the focus of this article is not to introduce Kafka, not much to say). Kafka usage scenarios are still relatively large, such as buffer queues between asynchronous systems, and in many scenarios we will design as follo

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
