Percona Welcomes MySQL 5.6!

MySQL 5.6 was made generally available as a production-ready solution earlier this month. This release comes about 2 years after MySQL 5.5 was released, but MySQL 5.6 contains improvements started long before that – for example, work on the Innodb Full Text Search project was started over 6 years ago, in addition with many optimizer and replication features.

In this blog post, I will not go into a features overview of MySQL 5.6. You can check out Release Notes for a good overview as well as many blog posts and articles written on this matter. Instead, I will tell you what is the current state of things with MySQL 5.6 at …

How to use a smartphone for two-factor authentication with Percona Server for MySQL

In this post I will describe a non-trivial way to authenticate users in Percona Sever for MySQL. Percona Server comes with PAM authentication plugin, which allows you to do a lot of cool things, such as: OS authentication, LDAP authentication, even RSA Secure Server authentication (which is useful if you are required a PCI-compliance), and use Google Authenticator, which is the topic of this post.

You can use a smartphone for two-factor authentication with Percona Server for MySQL

With two-factor authentication a user is required to enter not only password, but to have an additional security token, which in the case with Google Authenticator can be your cell-phone (clients are available for Android, iPhone, Windows Mobile or BlackBerry with …

Feature in details: Incremental state transfer after a node crash in Percona XtraDB Cluster

With our newest release of Percona XtraDB Cluster, I would like to highlight a very nice ability to recovery a node and bring it back to the cluster with an incremental transfer after a crash.
This feature was available even in previous release, but now I want to give some details.

So, MySQL crashes from time to time and this a fact of life. HA solution is exactly needed to deal with an one node failure and allowing whole cluster continuing to work.

The idea is, if a node crashed, after it recovered – we just transfer all changes that happened in the cluster, while the node was down. It sounds easy in words, but proven hard when it comes to implementation. It all comes to the question: if mysqld crashes, how do we know what is the last transaction was executed. For a single InnoDB instance it is …

Feature preview: Compact backups in Percona XtraBackup

We continue to improve Percona XtraBackup, and today I would like to give a preview for one feature which comes in next Percona XtraBackup 2.1 release.

This feature is “Compact backups”, and let me explain what it does.
As you may know InnoDB PK (Primary Key) contains all data, and all secondary indexes are only subset of columns of Primary Key. So in theory we can store only PK, and re-build secondary indexes as we need. Well, now it is possible not only in theory.

To create a compact backup you should use
innobackupex --compact
and it will create a backup where all InnoDB tables contain only Primary Keys and not secondary.
It allows to safe some space on a backup storage. How much? Well, it depends on how many indexes you have.
