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 replication: Requests Binlog to Master when slave is ready. Cons: There is no guar

Explain how MySQL implements master-slave replication, and explain how mysql implements master-slave replication. 1. What is master-slave replication? The DDL and DML operations in the primary database are transmitted to the slave database through binary logs, and these logs are re-executed (redone ); so that the data in the slave database is consistent with that

Of course, the appearance of the 5.6 GUID feature also brings the infinite possibility of multi-master, but this is the digression.

　 Master Pages)Http://blog.csdn.net/iiboy/ One of the most prominent disadvantages of ASP. NET 1.x is that it lacks support for page templates. What is lacking is the ability to define "master pages" that can be inherited by other pages. Developers make up for this by using user controls (which can be easily copied between pages) to create pages. In ASP. NET 2.0, this technique is no longer needed because

1. IntroductionAs one of the most widely used databases in the world, MySQL is one of the reasons why it is free. But what is not to be overlooked is that its own function is indeed very powerful. With the development of technology, in the actual production environment, the single MySQL database server can not meet the actual demand. At this point the database cluster is a good solution to this problem. With MySQL distributed cluster, you can build a high-concurrency, load-balanced cluster Serve
