Traditionally replication has been monitored using the information in SHOW SLAVE STATUS, however it doesn't always represent the full picture. This presentation will outline how combining different methodologies it is possible to obtain a more accurate picture about replication health.
In this session, I will talk about tough DBA tasks - how to automate failover under non-trivial crash situations (i.e. promoting one of slaves to new master), and about how to eliminate downtime for difficult maintenance tasks (i.e sharding). If you have spent too much time for these tasks, this session will help your DBA life easier.
Keynote by Jeremy Cole, DBA Team Lead and MySQL Architect, Twitter.
While databases are increasingly being distributed across multiple nodes, the performance of every node still matters--especially if you're considering virtualized or cloud deployments that have their own specific trade-offs. Memory performance scaling as core count changes, all aspects of disk performance, and using sysbench to benchmark both MySQL and PostgreSQL are all topics covered here.

AOL deployed its large scale Real Time News (RTN) system in 2007. This system receives news updates from over 30,000 sources on every second around the clock. Today, its data store, MySQL, has accumulated over several billions of rows and terabytes of data. However, news are delivered to end users in close to real time fashion. This presentation shares how it is done and the lessons learned.
The last few years have brought technological and market shifts that have disrupted open-source databases. These include cloud computing, solid-state storage, non-SQL databases, and MySQL's acquisition. In this keynote presentation, Baron Schwartz will discuss the new reality
that faces open-source database users and developers.
Elasticity is a key characteristic of public, private and hybrid clouds. Virtual machines can be spun up and spun down at a moment's notice. But how do databases behave in clouds?
Production schema changes are painful but unavoidable. This session will tell you how to
minimize (or totally eliminate) downtime during schema changes with master-master setup or by using "shadow" tables.
Session will focus on pros and cons of each approach and describe most common use cases.
