Live Webinar: What MySQL replication cannot do. And how to get around it.

Thursday, January 27, 10 am PT/1 pm ET

MySQL built-in replication is the greatest component of the web economy, Its model of scaling out has allowed the growth of companies such as Google, Yahoo!, Facebook, Wikipedia, and countless more. However, this simple model has limitations. Some you can live with, and some will send DBAs in a quest for other tools, from which they often come back empty handed.

This webinar covers some of these limitations, and how Tungsten can overcome them:
  • Multiple source replication, also known as the headquarters that wants to synchronize data from its branches. Impossible to do with MySQL. An easy job for Tungsten.
  • Automatic slave promotion and demotion, both for failure recovery and maintenance. In MySQL it requires manual synchronization of data, and sometimes results in data loss. For Tungsten, it is child's play.
  • Seamless upgrade of replicated servers. You can do that in MySQL, but it's all manual and error prone labor. Tungsten simplifies the task and makes it safer.
  • Parallel replication. In MySQL, slaves must queue all their transactions into a single thread. Tungsten allows parallel replication per database, speeding up the data transfer way faster than native replication.
