, Sendfile Kafka consumption does not lose the mechanism. Producer, broker, consumer. Kafka consumer data is globally ordered. The individual partition is orderly, the global order violates the design original intention. Streaming calculation framework (Storm) The composition of the streaming computing framework: General Flume+

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
