This article mainly introduces "what are the characteristics of the MGR cluster in MySQL". In the daily operation, I believe that many people have doubts about the characteristics of the MGR cluster in MySQL. The editor consulted all kinds of materials and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "what are the characteristics of the MGR cluster in MySQL?" Next, please follow the editor to study!

High consistency: group replication based on distributed paxos protocol to ensure data consistency

High fault tolerance: automatic detection mechanism, as long as not most of the nodes are down, can continue to work, built-in anti-brain fissure protection mechanism

High scalability: the addition and removal of nodes automatically updates the group member information, and after the new node is added, the incremental data is automatically synchronized from other nodes until it is consistent with the data of other nodes.

High flexibility: provides single-master mode and multi-master mode. Single-master mode can automatically select master after the main database is down. All writes are carried out on the master node, and multi-master mode supports multi-node writes.

At this point, the study on "what are the characteristics of MGR clusters in MySQL" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
