Many programmers do not fully understand the visibility and secure release of a shared variable during initialization (building an object securely and correctly accessing other threads, java is a platform that shields memory details and does not need to be concerned about object recycling. Therefore, most of the visibility and Security releases are published on Alibaba Cloud. In fact, the key lies in the Ja

With the evolution of high-performance computing from traditional host to networked cluster, the traditional host-based storage architecture has gradually developed to networked storage, and the trend of computing and storage separation is becoming more and more obvious. In view of the shortage of SAN and NAS, the research of the new file system-
