This morning, this Percona XtraBackup bug came to my attention: https://bugs.launchpad.net/bugs/1170340 - basically, it’s now really quite tricky to determine if a MySQL server you’re connected to supports partitioning or not.

If you’re connected to anything less than MySQL 5.6, you can use have_partitioning variable. But since that’s gone in 5.6, you’re going to get a false negative if you’re connected to 5.6. You could use INFORMATION_SCHEMA.PLUGINS table, but that’s not there in 5.0, so you have some added workarounds to add there too.

A simple version check could be the solution… but what if you compiled the server without partitioning support?

There’s an Indiegogo fundraising effort for Julian Cash to come to the Percona Live MySQL Conference and Expo this year to take your photo! I’ve thrown in a bunch of money to help make this happen. Why? It’s much much much cheaper than getting any professional photo shoot done, and it’s by the awesome Julian, who makes pretty awesome photos.

You’ll get full resolution images too! Basically, this is the cheapest way you’re going to get this quality of photos done of yourself outside of dating a professional portrait photographer. Since I’m not dating a professional portrait photographer, this is an excellent and affordable way to have some truly …

Come see out new cool ‘cryogenic dolphin’ at the MySQL Community Reception Monday. Come hear about the latest 5.6 news from MySQL Engineers, see Cluster on Raspberry Pis, and walk away with our giveaways. And did I mention it is FREE?!?!

Here’s the last nail in the coffin. We hope this convinces you not to write to multiple masters with MySQL replication. Reason 10 – No tools to reconcile inconsistent masters For all the endless reasons we’ve already outlined MySQL replication is prone to failure. We know it’s going to happen, you now know too. When [...]

If you’re not convinced yet that writing to dual masters is a bad idea, we have a couple more reasons. 9. Temp tables break replication after restart MySQL’s replication is sensitive to temporary tables. You shouldn’t use them. If your queries create them to work against, and a node crashes, the temp tables will be [...]

Writing to two masters is like walking around with a loaded shotgun. Eventually one of your instances will fail and when it does, replications position & synchronization information could easily become corrupt! Reason 8 – Crashed nodes cause big problems MySQL instances, unfortunately can crash. When that happens, they don’t always sync the replication position [...]

Among the myriad data integrity and corruption risks associated with active-active replication, you also lose out on configurability and operational flexibility. Reason 7 – Can’t add nodes easily The often touted solution to use auto_increment_increment and auto_increment_offset fixes you to a given setup forever. You can set it up with a discrete two nodes, all [...]
