Oracle MySQL Group Replication

../../_images/MySQLMultiRegion.PNG

  • MySQL Enterprise allows for the database to be configured in an Active/Active Regional Multi-Data Center architecture.

  • This setup provides high availability, disaster tolerance and low latency access to users around the globe.

  • Because data centres are far apart and networks connecting have high latency, asynchronous master/slave replication is carried out between each site and cluster.

  • However, because there is no automatic conflict detection and prevention, the application needs to ensure write are conflict free.
