MySQL5.6同步白皮书
MySQL Replication enables users to cost - effecti vely deliver application performance, scalability and
high availability. Many of the world's most trafficked web properties like eBay, Facebook, Tumblr,
Twitter and YouTube rely on MySQL Replication to elastically scale- out beyond the capacity
constraints of a single instance, enabling them to serve hundreds of millions of users and handle
exponential growth.
By mirroring data between instances, MySQL replication is also the most common approach to
delivering High Availability (HA) for MySQL databases. In addition, the MySQL replication utilities can
automatically detect and recover from failures, allowing users to maintain service in the event of
outages or planned maintenance.
With the release of MySQL 5.6, a number of enhancements have been made to M ySQL Replication,
delivering higher levels of data integrity, performance, automation and application flexibility. We will
discuss these enhancements in the whitepaper.
We will also explore the business and technical advantages of deploying MySQL Replic ation and
describe the fundamental enabling technology behind replication .
This paper concludes by outlining the major differences when using replication with the MySQL
Cluster database.
A companion white paper (MySQL 5.6 Replication – Tutorial
1
) provides a simple step - by- step guide
on how to install and configure a master/slave topology, as well as handle failover events . It
demonstrates how to do this using Global Transaction Identifiers (GTIDs) as well as the extra steps
needed when taking the more traditional approach.
