Message Queuing can reside in memory or on disk, and queues store messages until they are read by the application. With Message Queuing, applications can execute independently-they do not need to know each other's location, or wait for the receiving program to receive

The Publish/Subscribe feature makes the coupling between sender and receiver looser, the sender does not have to care about the destination address of the receiver, and the receiver does not have to care about the sending address of the message, but simply sends and receives the message based on the subject of the message.

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
