As you may know I closely follow Galera replication development, and right now I am evaluating how it performs in our benchmarks. Of course my closest interest is Percona Server, so I made port of Galera from MySQL/InnoDB-plugin to Percona Server 5.1.57. Right now it is only in source code https://code.launchpad.net/~vadim-tk/percona-server/percona-galera-5.1.57, but it brings couple good things:
- It is based on Percona Server with XtraDB, with all its performance and diagnostic improvements
- It contains scripts for xtrabackup node propagation, which provides minimal impact on the cluster when new node joins
You are welcome to try it, however it is not recommended to use in production, as my port is on very early stage yet.
If it shows good result in evaluation, we are going to provide Percona Server binaries with Galera replication module.
