[Read more]Yesterday we announced the GA release of Percona Server 5.6, the latest release of our enhanced, drop-in replacement for MySQL. Percona Server 5.6 is the best free MySQL alternative for demanding applications. Our third major release, Percona Server 5.6 offers all the improvements found in MySQL 5.6 Community Edition plus scalability, availability, backup, and security features some of which are found only in MySQL 5.6 Enterprise Edition.
Percona Server 5.6 comes with:
I occasionally see customers who are taking backups from their PXC clusters that complain that the cluster “stalls” during the backup. As I wrote about in a previous blog post, often these stalls are really just Flow Control. But why would a backup cause Flow control?
Most backups I know of (even Percona XtraBackup) take a FLUSH TABLES WITH READ LOCK (FTWRL) at some point in the backup process. This can be disabled in XtraBackup (in certain circumstances), but it is enabled by default.
If you go to your active cluster right now an execute a …

[Read more]I recently blogged on setting up Experimental Git mirror of Oracle MySQL trees up on GitHub. I’m now happy to announce that there are also mirrors for:
I’ve also updated the Oracle MySQL GIT mirror to include MySQL 5.7 and the (now abandoned) MySQL 6.0. I include the abandoned 6.0 tree as it can provide useful archaeology as to where some code came from.
I’d love to hear about any positive/negative experiences using these mirrors. Hopefully shortly I’ll fix up the last …
[Read more]Percona XtraDB Cluster (PXC) is different enough from async replication that it can be a bit of a puzzle how to do things the Galera way. This post will attempt to illustrate the basics of setting up 2 node PXC cluster from scratch.
Requirements
Two servers (could be VMs) that can talk to each other. I’m using CentOS for this post. Here’s a dirt-simple Vagrant setup: https://github.com/jayjanssen/two_centos_nodes to make this easy (on Virtualbox).
These servers are talking over the 192.168.70.0/24 internal network for our example.
jayj@~/Src $ git clone https://github.com/jayjanssen/two_centos_nodes.git jayj@~/Src $ cd two_centos_nodes jayj@~/Src/two_centos_nodes $ vagrant up Bringing machine 'node1' up …[Read more]

It’s available here: http://www.percona.com/downloads/TESTING/Percona-TokuDB/.
If you are interested, please test it and provide us with feedback. If things look good, in couple months we may release an official Percona Server 5.6 with TokuDB.
