Kafka is a distributed platform; it runs as a fault-tolerant, highly available cluster that can span multiple servers and even multipledata centers. Kafka topics are partitioned and replicated in such a way that they can scale to serve high volumes of simultaneous consumers without impacting perfo...
Kafka makes sure that the message is ordered within the partition in a round-robin fashion, but not beyond partitions in a topic. Producers can add the key to a message. So all messages with the same key will go to the same partition. Language Apache Kafka is developed in JAVA and Scala...
在kafka中,一个partition中的消息只会被group中的一个consumer消费;每个group中consumer消息消费互相独立;我们可以认为一个group是一个"订阅"者,一个Topic中的每个partions,只会被一个"订阅者"中的一个consumer消费,不过一个consumer可以消费多个partitions中的消息.kafka只能保证一个partition中的消息被某个consumer消费...

Partitions:Each partition is an ordered, immutable sequence of records that is continually appended. Partitions allow Kafka to parallelize processing as each partition can be consumed independently. Imagine Kafka as a highly efficient mail system. Producers are like senders dropping off letters (messages...
The consumer side of Kafka also has a fail-safe mechanism. You can create multiple instances of a consumer application to read messages from the same topic. Together, these instances make up aconsumer group. Each partition is assigned to one consumer in the group. In our example, one consume...
When data skew occurs on different partitions of Kafka, the executor corresponding to the partition with a large amount of data touches the glass ceiling of data processing. Therefore, when the Producer program is executed, data is sent to each partition on average to improve the processing speed...

kafka的生产者 1. 生产者客户端开发 熟悉kafka的朋友都应该知道kafka客户端有新旧版本,老版本采用scala编写,新版本采用java编写。随着kafka版本的升级,旧版本客户端已经快被完全替代了。因此,我们以新客户端为例进行介绍。 客户端开发的步骤如下: 配置
