Label:Oracle's cluster and cluster tablesA cluster consists of a group of tables that share the same data block, which stores the related rows of those tables in the same data block, which reduces the amount of disk reads required to query the data. After the cluster is created, users can create tables in the

Recently, a colleague tested the performance of Supermap iServer Java 6R. When asked about cluster configuration and the concept of In-process clusters, simply configure and test it by yourself. This is the second article of Supermap iServer Java 6R cluster research. In Supermap iServer, the GIS functions provided by service providers are encapsulated into coarse-grained modules by service components a

I'm stupid enough to figure out what a horizontal cluster is and what a vertical cluster is today.A vertical cluster is the installation of multiple application servers on a single machine. or a cluster on the same server, presumably:A horizontal cluster is the installation

HA (High available) High Availability cluster ( two-machine hot standby)1. Understanding: Two servers A and B , when a service, B idle standby, when a service outage, will automatically switch to the B machine to continue to provide services. When the host is back to normal, the data consistency is resolved through the shared storage system by automatically or manually switching to the host as set by the user.2. The software that implements this func

MongoDB cluster technology: replica set sharding, mongodb ClusterA MongoDB replica set is a process of synchronizing data to multiple servers. The replica set provides redundant backup of data and stores data copies on multiple servers, this improves data availability, ensures data security, and allows data recovery from hardware faults and service interruptions.Mongodb replication requires at least two nodes. One of them is the master node, which is
