the number of I/O on the serverData CompressionKafka also supports compression of message collections, producer can compress a collection of messages in gzip or snappy formatThe advantage of compression is to reduce the amount of data transmitted and reduce the pressure on the network transmission.Producer compression, the consumer needs to be decompressed, although the work of the CPU increased, but on the big data processing, the bottleneck on the network rather than the CPU, so this cost is

Summary: AWS (Amazon Web Services) is one of the world's leading cloud server providers. You can use the AWS platform to set up your servers within a minute. On AWS, you can fine-tune many of the technical details of the server, such as the number of CPUs, memory and disk space, the type of disk (faster SSD or classic IDE), and so on.AWS (Amazon Web Services) is

VMware requires enterprise customers to continue to use vsphere and renew their enterprise license agreement. Because VMware does not sell hardware, it relies on revenue from licensing, support, and services. That's why you work with AWS. Based on the cooperation agreement, AWS will provide hardware, and VMware will provide software, support, and services. 2016, one thing you can't imagine: V
