Create a ThemeGo to the Kafka directory and create the "TEST5" topic topic: Partition 3, Backup to 3192.168.6.56:2181,192.168.6.56:2182,192.168.6.56:2183 --replication-factor 3 --partitions 3 --topic test5

write, combined with the characteristics of zero-copy greatly improve the IO performance. However, this is only one aspect, after all, the capacity of stand-alone optimization is capped.How to increase throughput further by horizontal scaling or even linear scaling? Kafka uses partitions (partition) to achieve high throughput of message processing (whether producer or consumer) by breaking topic messages t

the Kafka normally. The final symbol of the command is to allow the launcher to execute in the background. If you do not add this symbol, we will usually use CTRL + C to exit the current console when the boot is finished, and Kafka will automatically execute the shutdown, so it is best to add the symbol here.Third, use basic commands to create message topics, send and receive

Thanks for the original English: https://www.confluent.io/blog/how-to-choose-the-number-of-topicspartitions-in-a-kafka-cluster/ This is a frequently asked question for many Kafka users. The purpose of this article is to explain several important determinants and to provide some simple formulas. more partitions provide higher throughput the first thing to understand is that the subject partition is the unit

whereabouts, we can the Enterprise Portal, the user's operation records and other information sent to the Kafka, according to the actual business needs, can be real-time monitoring, or do offline processing. Finally, one is log collection, similar to the Flume suite, such as the log collection system, but the Kafka design architecture uses push/pull, suitable for heterogeneous clusters,

What is Kafka? Kafka, originally developed by LinkedIn, is a distributed, partitioned, multi-replica, multi-subscriber, zookeeper-coordinated distributed log system (also known as an MQ system) that can be used for Web/nginx logs, access logs, messaging services, etc. LinkedIn contributed to the Apache Foundation and became the top open source project in 2010. 1.

do not require high complexity. However, because the data volume is huge, not a few servers can meet the requirements, dozens or even hundreds of servers may be required, and performance requirements are high to reduce costs, therefore, the MQ system must be well scalable. Kafka is an MQ system that meets SaaS requirements. It improves performance and scalability by reducing the complexity of the MQ system.2. Kaf
