High MySQL Availability Based on MHA and Galera Cluster MHA: Master HA is an open-source MySQL high-availability program. It provides the automatic master failover function for the MySQL Master-slave replication architecture. When MHA detects a master node failure, it will escalate the slave node with the latest data to the new master node. During this period, MHA will obtain additional information on the slave node to avoid consistency issues. MHA al

follows:1. Adding a new node is a big expense. You need to copy the full data.2. Unable to effectively resolve the write scaling problem, all write operations will occur on all nodes.3. The number of nodes there is the number of duplicate data.The architecture diagram is as follows:The difference between Percona XtraDB cluster and MySQL replication is:Cap theory for Distributed systems:C-Consistency, the data of all nodes is consistent;A-availability
