Percona at PHP Quebec 09


Percona presented two talks at PHP Quebec last week – one on A Tour of MySQL High Availability, and another on Performance Tuning MySQL. There was a great reaction to showcasing some of the quick-wins that can be found by using the Percona patches. Unfortunately, the one thing that I forgot to mention in the slides is that the patches are Open Source and free to use.

    What is your/Percona’s opinion about Continuent’s Sequoia for MySQL HA?

    I find it odd that it seems absent from most discussions of MySQL HA.

    It offers synchronous replication. On paper it looks pretty good – I was put off by the documentation.

    Wondering if you guys have ever put it through its paces.

    @Jason – I’ll be honest, I don’t have any experience with it.

    I’m normally more of a fan of HA solutions that provide the functionality behind MySQL, rather than as a proxy in front of it. But my rationale for this is mainly just for ease of use, since it’s easier to retrofit and guarantee that all statements will still behave the same (for the same reasons the mysql statement based binlog has limitations / behaves like it does with RAND()/NOW(), etc.).

    You could probably group solutions like Sequoia with what I expect people will start using MySQL Proxy for as well. How do these solutions stack up? I haven’t tested yet myself – nor seen much out there yet.

    Great set of slides – very useful for someone who hasn’t played with indexes that much; looking forward to some speed increases!
