I. BACKGROUND When you build SQL Server replication, if the network environment is within the LAN, through the host name can be achieved, but if it is across the network segment, across the computer room to build replication when you need to pay attention to, because SQL

the security of the data and also causes a certain amount of delay, which is at least a TCP/IP round-trip time. Therefore, semi-synchronous replication is best used in low latency networks. relay Log Relay logs : In salve, the IO thread pulls master's binary to relay log, and the SQL thread reads the contents of the Relay-log log and applies it to the slave

. [The performance loss of only one connection is certainly larger than in the case of many connections. Keep in mind that you can work in parallel, network latency does not use more of our I/O or CPU bandwidth, so we can reduce the impact of slow transactions by initiating more concurrent work. ] When using synchronous replication, how can you ensure that performance does not suffer too much? Basically, th

Experiment MySQL with the plug-in provided by Google, complete the semi-synchronous replication model;The physical machine is still the Win7 system, the virtual machine is centos7;Master node: 192.168.255.2From node: 192.168.255.3Configure the primary from the replication model first:On the master node:]# vim/etc/my.cnf650) this.width=650; "src=" Http://s5.51cto.

. But you have to be careful when you are creating the following actions if your database is in simple recovery model and is part of replication as output of these actions will not be replicated Create Index Truncate table BULK INSERT BCP Select... The reason... well the replication engine will not be able to pick up these changes as these changes will only log page allocations and de-allocations.

In-depth analysis of semi-synchronous and asynchronous MySQL master-slave replication configurations, In short, MySQL master-slave replication is a C/S architecture application. The master can be considered as the server in the general sense, and the slave can be considered as a client. The I/O thread on the slave requ

The ultimate goal of replication is to keep the data of one server in sync with the data of another server, which has reached data redundancy or service load balancing. A primary server can connect to multiple slave servers, and from the server it can also be the primary
