MySQL cluster introductionMySQL clustering technology provides redundancy for MySQL data in distributed system, and enhances security, so that single MySQL server failure does not have a huge negative effect on the system, and the stability of the system is guaranteed.A MySQL cluster requires a set of computers, and the roles of each computer may be different. There are three types of

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

ObjectiveWhen your business arrives at a certain amount of the equivalent, you certainly need a certain number of databases to load balance your database requests, I have explained in the previous blog, how to achieve load balancing, but there is also a problem is data synchronization, because the premise of load balancing is that each server database is data synchronization. When the volume of business is small, we will use the master-slave replication method to achieve server data synchronizat

As more and more application architectures are decoupled and distributed, the requirements and dependencies of load balancer devices are increasing while the component scale-out capability increases, and the load-balancing devices are required to have strong scale-out capability. Load balancing clustering technology is becoming more and more important. While many vendors offer a variety of cluster technologies, the only netscaler that can really simpl
