[Redis] 3. Redis cluster deployment and redis cluster deployment A Redis cluster is an assembly that provides data sharing among multiple Redis nodes.Redis clusters do not support the processing of multiple keys commands, because this requires moving data between different nodes, so as to achieve performance like Redis, unexpected errors may occur under high load

-performance computing clusters are used in the field of scientific computing by allocating computing tasks to different computing nodes of the cluster to improve computing power. The more popular HPC uses the Linux operating system and some other free softTo complete the parallel operation. This cluster configuration is often referred to as Beowulf clusters. Suc

Becker said that the Linux cluster system should pay more attention to the development of virtual technology and high feasibility, and explained the reasons in his interview. At the same time, he gave some suggestions to users who switched to Linux cluster Symmetric Multi-processing. Besides his role in Beowulf, Becker is also the founder and main scientist of Sc

Fragmentation of the cluster When a cluster is split into several individual groups due to network reasons (a group may be a single node or several interconnected nodes), the data is inconsistent and may result in brain fissures and inconsistent data. In this case, only one set of nodes can continue to serve, the state of this set of nodes is primary. When this happens, Galera
