Big Transactions on Galera Cluster,  15 April 2:00PM – 2:50PM @ Ballroom B (click here for more info)

Seppo Jaakola,  CEO, Codership

Big and long term transactions have traditionally not behaved well in Galera Cluster. Large replication data sets have resulted in symptoms like elevated conflict rate, increased memory consumption, even OOM kill may happen, flow control pausing, cluster freezing… To deal with these issues, Galera users have been adviced to split large transactions in “reasonable size”. There is also cluster configuration option for rejecting too large transactions, as a safe guard.

Percona Live London Keynote:

Synchronous Revelation (by Alexey Yurchenko) 4 November 9:40am – 10:05am

What is synchronous replication? For many it is just the same as asynchronous, only safer and slower. But is it all that is to that? (At this point you’re probably guessing “no?”) In this talk Alex will ponder eternal questions: what is “synchronous”? is it “replication”? and how new MySQL server UUIDs are relevant to that?

Galera presentation Wednesday 5th, 11.30 on Demotheater stage: Designing for Scale: Data Storage in OpenStack and Galera Cluster By Jay Pipes,  Mirantis

The foundation of your OpenStack deployment is composed of the data stores you use for the various types of data that flow through the OpenStack componentry.

Before you deploy OpenStack, spend some time thinking about how to build on a good foundation. In this session, we will analyze the numerous OpenStack components with an eye for how the data each component produces and consumes is stored in …

Need to add phone and SMS alerting to ClusterControl? ClusterControl 1.2.8 introduces support for PagerDuty, an alerting service for Ops teams to schedule on-calls and add phone and SMS notifications to IT tools. By integrating PagerDuty with ClusterControl, you can start receiving phone, SMS and email notifications for all important database events as monitored by ClusterControl. Alerts go directly to the right person who can solve the issue.

This integration is possible thanks to a new plugin interface, that takes ClusterControl alarms in JSON format and outputs to an external system via plugins. Plugins can be either scripts or executable binaries.
