#Galera集群特点 No delay between clusters, synchronous replication. While Master-slave master-slave asynchronous replication, there is a delay. Active-active Multi-master, the cluster internal server is written at the same time, must wait for all the databases in the cluster to complete the data write, the feedback is complete, so there is no data loss situation. The

Zookeeper practices: Zookeeper cluster mode for Embedded running, zookeeper ClusterMany Zookeeper scenarios require that we embed Zookeeper as part of our distributed application system to provide distributed services. In this case, we need to start Zookeeper through a program. In this case, you can use the ZooKeeperServerMain class of the Zookeeper API to start the Zookeeper service.The following is an example of starting the Zookeeper service in
