The previous article thanks to "Mysql, MariaDB traditional master-slave cluster Configuration", the technology has been very mature. Starting from Mysql5.6 and MariaDB10.0, with the new master-slave scheme Gtid, but the two systems to this version of the branch, the implementation has been different, configuration methods are different, the following are described separately.MariaDB:I use the version is sti

node in our cluster. A replica set is a node for cluster. Because at any moment, only the primary in the replica set can accept the write operation. So in order to play cluster , we need to add more than one replica set so that MONGOs can read and write multiple replica sets in parallel. Refer to the replica set deployment document to create the new replica set

By moving applications on a failed server to a backup server, the cluster system can increase uptime to more than 99.9%, significantly reducing server and application downtime.High manageability: System administrators can remotely manage one or even a group of clusters as if they were in a standalone system."Disadvantage"We know that the application in the
