technical field
[0001] The present invention relates to the technical field of communications, and in particular to a performance optimization method, device, equipment and computer-readable storage medium. Background technique
[0002] Hadoop is an open source distributed computing platform. Hadoop Distributed File System (Hadoop Distributed File System, HDFS) is a core component of Hadoop and is currently widely used in big data services. HDFS is mainly responsible for storing file data in Hadoop. Files on HDFS are stored in blocks. A data block is an abstraction that is a logical unit of file storage processing. A data block usually has multiple copies to increase data security, and multiple copies of the data block are usually stored in different data nodes, and these data nodes may be in the same rack or in different racks. When a client in HDFS wants to read a file, it usually prefers to read the copy of the data block in the data node closest to it, such as reading...
