Abstract: Managing High-Volume Replication Tiers for High Availability

  Replication is a very powerful technique that can be used to generate
  both high availability and scalability for applications. Maintaining a
  replica of a MySQL database is a good way to build in a disaster
  recovery scenario for your application. Maintaining multiple replicas
  allows you to create highly available applications. It is also a way of
  scaling an application to be able to service a larger number of users,
  queries and/or connections. While implementing a system to obtain the
  benefit of high availability and scalability is feasible, there are
  some downsides that can be all too common. This talk will discuss some
  of these common problems and their causes, such as why too high a
  volume of transactions can overwhelm the replication process. It will
  discuss some of the current techniques that are being used to solve
  these problems and review the pros and cons of each approach. Finally,
  it will explore alternative approaches that can be implemented to solve
  common problems without resorting to application changes or other
  tradeoffs. Specific replication management functions will also be
  described and user case studies will be highlighted to demonstrate
  "real-world" implementations.
