MySQL semi-synchronous replication and mysql Synchronization MySQL supports semi-synchronous replication as a plug-in starting from MySQL5.5. How can we understand semi-sync? First, let's look at the concept of Asynchronization and full synchronization. Asynchronous replication) By default, MySQL replication is asynch

1. Overview of Replication 1.1 problems solved by ReplicationData replication technology has the following features:(1) Data Distribution(2) load balancing)(3) backup(4) high availability and fault tolerance 1.2 How replication worksFrom a high-level perspective, replication is divided into three steps:(1) The master

Copy is also called copy. We do not know how many operations are performed every day, but do you really use it? Sometimes, simple copy operations may also encounter some minor issues: the copied text is changed to garbled, encrypted Web pagesArticleCannot be copied. How can we solve these problems? This article will show you an answer, and you can also see how to speed up replication and other related skills. Required Course for copying 1. learn f

A replication environment requires only two hosts running MySQLServer, or even simpler, we can start two mysqldinstance on the same physical server host, one as Master and the other as slave to com

The ORACLE tutorial is: A Brief Discussion on the Oracle database set replication method. PrefaceThe increasing demand for distributed applications requires a better distributed software environment, which constantly promotes the development of distributed technology. Oracle Data replication is a technology that implements a distributed data environment. It creates a distributed data environment by copying

Label:The architecture of replication has the following basic principles:(1) Each slave can have only one master;(2) Each slave can only have a unique server ID;(3) Each master can have a lot of slave;(4) If you set Log_slave_updates,slave to be the master of other slave, it will spread the update of master. MySQL does not support multi-master server replication (multimaster

1. Database Replication SQL Server 2008 database replication synchronizes data between multiple servers through the publishing/subscription mechanism. We use this mechanism for Synchronous database backup. The synchronous backup here refers to the real-time data synchronization between the backup server and the master server. Normally, only the master database server is used, and the backup server is only u

Redis's master-slave copy strategy is realized through its persistent RDB file, the process is to dump out Rdb file, Rdb file to Slave, and then synchronize the operation of the dump to slave in real time. The following is an article on the principle of Redis reproduction, the author of the article for Sina Weibo Tianqi classmate (@ Rocking Bach). This article discusses the replication capabilities of the Redis and the advantages and disadvantages of
