下面是一些关于Apache kafka 流行的使用场景。这些领域的概述，可查看博客文章。

Messaging

消息

　　Kafka works well as a replacement for a more traditional message broker. Message brokers are used for a variety of reasons (to decouple processing from data producers, to buffer unprocessed messages, etc). In comparison to most messaging systems Kafka has better throughput, built-in partitioning, replication, and fault-tolerance which makes it a good solution for large scale message processing applications.

kafka更好的替换传统的消息系统，消息系统被用于各种场景（解耦数据生产者，缓存未处理的消息，等），
与大多数消息系统比较，kafka有更好的吞吐量，内置分区，副本和故障转移，这有利于处理大规模的消息。

　　In our experience messaging uses are often comparatively low-throughput, but may require low end-to-end latency and often depend on the strong durability guarantees Kafka provides.

根据我们的经验，消息往往用于较低的吞吐量，但需要低的端到端延迟，并需要提供强大的耐用性的保证。

　　In this domain Kafka is comparable to traditional messaging systems such as ActiveMQ or RabbitMQ.

在这一领域的kafka比得上传统的消息系统，如的ActiveMQ或RabbitMQ的。
