Recently research producer load Balancing strategy,,, I in the Librdkafka in the code to implement the partition value of the polling method,, but in the field verification, his load balance does not work,, so to find the reason; The following is an article describing Kafka processing logic , reproduced here, study a bit.Apache Kafka series of producer processing logicTags:

as a stream processor, receive an input stream from one or more topics, output a stream of one or more topics, and effectively convert an input stream into an output stream.The Connector API allows you to build and run reusable producers or consumers, connecting message topics to applications or data systems. For example, a connection to a relational database can get all changes to a table. Kafka's client-to-server communication uses a simple, high-p

The producer publishes the data to the subject of their formulation, and the producer is responsible for selecting which partition in the topic. This can be done simply by looping the load, or by using semantic partitioning (which marks the keyword in the record). Consumers Consumer The consumer uses the group name tag, and each record published to the subject is received by all members of the group that has subscribed to the topic. Consumer instance

broker in Producerpool. Every 10 minutes of refresh will re-rebuild the socket connection to each broker directly, meaning that the first request after that will have a hundreds of millisecond delay. If you do not want the delay, change the topic.metadata.refresh.interval.ms value to-1 so that it is refreshed only if the send fails. Kafka cluster If a partition is located in the broker is hung, you can check the error after restarting rejoin the clus
