Label:5.2 Understanding actual impact and performanceIn this chapter, we have discussed the actual impact as well as the performance impact. But is there any good theoretical example? Let's do a simple benchmark test to see how replication is done. We do such tests to show you that the levels of endurance are not just a minor topic, but they are critical to performance. Let's assume a simple test: In the following scenario, we have connected to two eq

compatible. This means that newer servers can be slave servers of older versions. Replication usually does not significantly increase the server overhead. It requires the master server to enable binary logs. Replication is good for extended reading. You can direct the read to the slave server. 2. Why do I need semi-synchronous

Before mysql5.5, MySQL replication was asynchronous, and there was a certain delay between the data in the master database and the slave database. In this way, there was a risk that when a transaction was written to the master database and submitted successfully, when the slave database does not obtain the BINLOG pushed by the master database, the master database goes down. For example, the BINLOG of the ma

After the 5.5 semi-synchronous replication, MySQL5.6 has optimized and improved it. Two of them are more important: it should be a big pleasure for O M personnel. After the 5.5 semi-synchronous replication, MySQL 5.6 has optimized and improved it. There are two important as

semi-synchronous replication requires the use of plug-ins, and master and slave nodes need to install plugins. After the plug-in is installed , configure system variables to enable and disable the semi-synchronous replication feature. 1. semi-synchronous implementation Prere

by the response mechanism, and the data transfer is not considered until the confirmation message is received, otherwise the transfer of the information will be automatically transferred, thus ensuring that all the extracted data can be sent to the backup side. The data transmission process supports both the encryption and compression functions.

SQL Server 2008 database replication is a publish/subscribe mechanism for synchronizing data between multiple servers, which we use for synchronous backups of databases.
