In this post I want to show new possibilities which open with Percona XtraDB Cluster.
We will create 3 nodes Cluster with nodes on different continents (Europe, USA, Japan) and each node will accept write queries.

Documentation is an important part of any project. On the projects I maintain I put a lot of effort on documentation, and, frankly, the majority of time spent on my projects is on documentation.
The matter of keeping the documentation faithful is a topic of interest. I'd like to outline a few documentation bundling possibilities, and the present the coming new documentation method for common_schema. I'll talk about any bundling that is NOT man pages.

Preparing Optimizing MySQL Configuration talk for Percona Live in Washington,DC I noticed how many Variables did MySQL get over years – it is pushing 400 these days even if we do not count variables/options which do not have matching SHOW VARIABLES value, and settings done by changing tables rather than command line options (like much of Performance Schema configuration). Innodb settings alone push 100.
