data from the slave node. In horizontally Scalable businesses, replication is easy to implement, mainly in the use of the master node for write operations, multiple slave nodes for read operations, in mysql5.5, the default is asynchronous replication. The Asynchronization of mysql replication means that a transaction

MySQL Semi-synchronous Replication (Semi-synchronous Replication) in enterprise applications, MySQL often uses a master-slave architecture or a master-master architecture to achieve load balancing of

MySQL replication is divided into master-slave replication and master-master replication. What is master-slave Replication refers to a master server with one or more servers as the slave servers. The slave server does not write any data. The data source is the master server.

MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary server, one or more servers as from the server. No data is written from the server, and the source of the data is the primary server. Th

Asynchronous replication: MySQL natively supports one-way, asynchronous replication. Asynchronous replication means there is a delay in copying data from one machine to another-most importantly this means that the data cannot be copied/applied to the slave at the same time when the application's transaction commit has

The ultimate goal of data replication is to synchronize the data of one server with the data of another server, which can achieve data redundancy or load balancing of services. A master server can connect multiple slave servers, and the slave server can act as the master server in turn. The master-slave server can be located in different network topologies. Due to the powerful mysql

Label:synchronous, asynchronous, semi-synchronous replication comparison:Synchronous replication: Master commits the transaction until the transaction is committed at all slave, and the client is returned, and the transaction is completed. Disadvantage: There can be a significant delay in completing a transaction.Asynchronous

As a result,
