This blog discusses the use of Apache Kafka® for data streaming, focusing on its pub-sub subscription model and asynchronous communication capabilities. It explains how producers append events to distributed logs called topics, while consumers consume data from these topics by offset. The producer/consumer or pub-sub model is ideal for loose coupling between components and asynchronous communication in scenarios like microservices architecture (MSA). The blog then demonstrates setting up an Aiven Kafka instance, implementing a producer and consumer, and running them together to illustrate the benefits of Apache Kafka®.
