1. What is Kafka?Kafka is a distributed MQ system developed and open-source by LinkedIn. It is now an incubator project of Apache. On its homepage, Kafka is described as a high-throughput distributed MQ that can distribute messages to different nodes. Kafka is compiled by only 7000 lines of scala. It is understood that

Prerequisites: 1: You may need to understand the logback log system. 2: You may need a preliminary understanding of Kafka. 3: Before viewing the code, please carefully refer to the business diagram of the system Because Kafka itself comes with the "hadoop" interface, if you need to migrate files in Kafka directly to HDFS, please refer to another blog post o

Problem DescriptionWhen processing with Kafka read messages, consumer reads the data in the Afka queue repeatedly. problem ReasonKafka's consumer consumption data will first read a batch of message data from broker to process, and then submit offset after processing. and the consumer consumption in our project is low, resulting in the removal of a batch of data in the session.timeout.ms time without processing completed, automatic submission offset fa

Kafka does not provide a high availablity mechanism in previous versions of 0.8, and when one or more broker outages, all partition on the outage cannot continue to provide services. If the broker can never be restored, or if a disk fails, the data on it will be lost. And Kafka's design goal is to provide data persistence, at the same time for the distributed system, especially when the cluster size rise to a certain extent, one or more machines down

1. OverviewAt present, the latest version of the Kafka official website [0.10.1.1], has been defaulted to the consumption of offset into the Kafka a topic named __consumer_offsets. In fact, back in the 0.8.2.2 Version, the offset to topic is supported, but the default is to store the offset of consumption in the Zookeeper cluster. Now, the official default stores the offset of consumption in Kafka's topic,
