Message interruption: Compared with most messaging systems, Kafka has better throughput, built-in partitioning, replication and fault tolerance, which makes it an ideal solution for large-scale message processing applications.Here are some applications that can take advantage of Apache Kafka: It is a container that contains several topics with partitions. Kafka proxy: Each server with Kafka installed is called a proxy.Each message is stored in the partition with an incremental ID (called an offset value). When creating a topic, you need to specify the number of partitions, but you can increase the number of partitions as needed in the future. Partitions: Each topic is divided into multiple partitions (“buckets”).For example, if you want to store all the data about the page that was clicked, you can specify a name for the topic, such as “page clicked.” Subject: The subject is the general name used to store and publish a specific data stream.You can check the deployed web application by going to the below URL. 16:34:40.367:INFO:oejsh.ContextHandler:Scanner-0: Started REST Webservice Example,/async-rest,AVAILABLE}
