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

Code implementation 3.1 Java ProjectIf you use the Java Project project to implement this part of the code, you need to add the relevant JAR file, whose contents include the following: Scala-xml_${

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

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
