Below we introduce the following 3 nodes: 2 nodes are mainly from each other, 1 nodes as the first 2 nodes from, for the implementation of MySQL5.6 3 node master-slave

. • III. The principle of replication The master node counts the actions in oplog, copies each document from the master node when the node is started, and then obtains the oplog of the master node and performs the operations in order to achieve data synchronization. Oplog is saved in the Local.oplog collection, the master node maintains a Syncedto property, the primary node passes through the Db.slaves.find (), and the node is db.sources.find () V

Original: HTTP://ANTIREZ.COM/NEWS/45 Author: Antirez Weblog As I wrote in a previous blog post, I am currently developing some of the resynchronization features of Redis slave. Our idea is that we have a backup log of the replication stream that can reach the specified number of bytes (by default it will be hundreds of megabytes). If a slave connection is lost, it will establish a connection again, see if the master's Runid is the same, and ask to c
