For backups, historically in the MySQL world you’ve had mysqldump (a SQL dump, means on restore you have to rebuild indexes), InnoDB Hot Backup (proprietary, but takes a copy of the InnoDB data files, so restore is much quicker), LVM snapshots (various scripts exist, does have larger IO impact, requires LVM) and more recently xtrabackup. Xtrabackup essentially does the same thing as InnoDB hot backup except that it’s free and open source software.

Many people have been using xtrabackup successfully for quite a while now.

In Drizzle7, our default storage engine is InnoDB. There have been a few changes, but it is totally InnoDB. This leaves us with the question of backup solutions. We have drizzledump (the Drizzle equivalent to MySQL dump – although with fewer gotchas), you could always use LVM snapshots and the probability of Oracle releasing InnoDB Hot Backup for Drizzle is rather minimal.

So enter xtrabackup as a …

Backups are an integral and very important part of any system. Backups allow you to recover your data and be up and running again, in the advent of problems such as system crashes, hardware failures or users deleting data by mistake. I had been evaluating backup solution for a while but to be honest I really wasn't satisfied with the solutions available until I came across XtraBackup and I am loving it since. In this post I intend on showing how to do backups and restores using XtraBackup.

Percona Server version 5.1.55-12.6 is now available for download. It is now the current stable release version.

Changes

• Fixed compiler warnings in both the core server and in XtraDB. (Alxey Kopytov, Yasufumi Kinoshita)

Bugs Fixed

• Bug #602047 – The ROWS_READ columns of TABLE_STATISTICS and INDEX_STATISTICS were not properly updated when a query involved index lookups on an InnoDB table. (Yasufumi Kinoshita)
• Bug #707742 – The server could crash when trying to import a table which had not been previously prepared using xtrabackup --prepare --export. Also, on servers with huge buffer pools, adding or removing an index even on an empty InnoDB table could take a long time due to excessive locking when …

Yesterday I wrote down the approach used in the MepSQL build system to parameterize the TAR package name produced. Today I will follow up with how the same was done for building DEBs. The motivation is to create a system that can be used flexibly to create packages of any MySQL fork, with any brand name: mepsql-server-*.deb, percona-server-server-*.deb, mariadb-server-*.deb or even just mysql-server-*.deb (which I might do some day).

While yesterday's tricks with the TAR files were rather straightforward, with the process of building DEBs this turns out to be much more challenging. But not to worry, like my former collague Bernhard Ocklin used to say: This is software, anything …

As I mentioned before, it seems that thanks to Git and Bzr introducing distributed version control workflows, the open source community is now living in a phase where forking is easy and happens frequently - referred to by Brian Aker as the Cambrian Explosion of open source. We certainly see that happening in the MySQL Community.

Assuming you have the competence and know your way around a codebase, forking a proper open source project isn't that hard. You create your own project on GitHub or Launchpad and copy the source code. 1 But one …

It’s finally here! Percona Server Percona Server 5.5.8-20.0 is now available for download. This is a beta release of Percona’s enhancements to the MySQL 5.5.8 server. Here are some highlights:

On Thursday, February 10, at 10am PST, there is a free webinar about Managing Big Data with Percona Server, XtraBackup and Tungsten. Quoting from the announcement:

Big data is a big problem for growing SaaS businesses and large web applications. In this webinar, we'll teach you how to set up Percona Server, XtraBackup, and Tungsten to manage Terabyte+ databases and scale to millions of transactions a day. We'll discuss the latest features for high transaction performance like InnoDB buffer pool dump/restore and HandlerSocket, our favorite tricks for backup, restore, and provisioning of large data sets, and how to replicate scalably and safely using Tungsten Replicator with parallel apply.

The presenters are representatives of both Percona and …

I wish I could be at this: Percona Live San Francisco. It is on February 16th. Cost is minimal, and content is maximal. The topic is on what’s new in MySQL these days beyond 5.1: the new 5.5 release, HandlerSocket, MariaDB, and of course Percona Server.

This is a follow-up to the enormously successful Percona Performance Conference in 2009.
