Codership team published beta2 of MySQL 5.5.15 with Galera replication https://launchpad.net/codership-mysql and we made port to Percona Server: source code: lp:~percona-dev/percona-server/percona-server-galera-5.5.15 binaries for RedHat/CentOS 6: https://www.percona.com/downloads/TESTING/Galera/Percona-XtraDB-Galera-5.5.15.tar.gz What difference between Percona Server+Galera and MySQL 5.5.15 ?

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 […]
