Tungsten Replicator version 2.0.6 was released today.
You can get both the binaries and the source code at the project's downloads page.
This release contains many bug fixes, and various improvements. All of them are listed in the Release Notes. The most interesting ones are the improvement in multi-master topologies. Using this release with star topologies you will get less traffic than before, because we have reduced some duplication of transaction history logs that were sent between servers.
And speaking of multi-master topologies, this release includes the cookbook recipes mentioned in this blog
[Read more...]From the desk of your new Bazaar plugin for Jenkins maintainer, I give you Version 1.18.
This release has two good bug fixes:
We’ve been running the same code as this release at Percona for about 2 months now (the second bugfix was one I wanted to test first before submitting upstream). This is the big fix that fixed all our problems with using bazaar with Jenkins in a large deployment.
[Read more...]We’re quite happy that we’ve released four major releases that are production ready (better known as generally available or GA in the MySQL world) in the last 26 months. That is just a little over two years, and a whole lot of features. In that same time, MySQL has seen one GA release (MySQL 5.5) and we’re all eagerly awaiting the upcoming MySQL 5.6.
You’ll note that we built MariaDB 5.1, 5.2, and 5.3 based on the MySQL 5.1 codebase. A significant number of features went into MariaDB 5.3 (our biggest GA release to date), with the biggest changes in the optimizer in over a decade. There were also many

We are pleased to announce the immediate availability of MariaDB 5.3.6. This stable (GA) release incorporates MySQL 5.1.62, some performance improvements, and several bug fixes.
Most importantly, MariaDB 5.3.6 includes a fix for a bug which, under certain rare circumstances, allowed a user to connect with an invalid password. This is a serious security issue. We recommend upgrading from older versions as soon as possible.

Following closely on the heels of the MariaDB 5.3.4-rc release a couple of weeks ago, the MariaDB project is pleased to announce the immediate availability of MariaDB 5.3.5!
MariaDB 5.3.5 is the first stable (GA) release in the 5.3 series. Details and downloads are available from the following links:
(Debian and Ubuntu packages are available from our mirrored apt repositories. A sources.list generator is available.)
The MariaDB 5.3 series introduces many new features,

It's been long known that Galera optimistic replication and enterprise-size databases are a match made in heaven. Today we're going to get a little closer to testing this statement.
We'll have look at how Galera can scale out Sysbench OLTP complex 60 million rows workload in EC2. This is a first proper benchmark for 0.8 series and also the first benchmark of MariaDB/Galera port, so I'll start modest, just to see how it goes. I chose m1.large instances with 7.8Gb of RAM for server nodes and c1.xlarge instance for a client - I don't want the client to be a bottleneck.
For comparison I have also measured performance of a stock standalone MariaDB 5.1.55 server. I used the standard my.cnf that comes with MariaDB Debian package with the following alterations:
max_connections=1024
innodb_buffer_pool_size=6G
innodb_log_file_size=512M

We’ve released Drizzle7! Not only that, we’re now calling it Generally Available – a GA release.
What does this mean? What does this GA label mean?
You could view as a GA label being “we’re pretty confident people aren’t going to on mass ask for our heads when they start using it”… which isn’t a too bad description. We also plan to maintain it, there could be future releases in this series that just include bug fixes – we won’t just immediately tell you to go and use the latest tarball or bzr tree. This release series is a good one to use.
Drizzle7 is something that can be packaged in Linux distros. It’s no longer something where the best bet is to add the

I am pleased to announce the availability of the MariaDB 5.2 feature preview release. Find the details and download links on the knowledgebase.
There has been quite good interest in the replication work I have been doing around MariaDB, and I wanted a way to make it easy for people to use, experiment with, and give feedback on the new features. The result is this replication feature preview release. This will all eventually make it into the next official release, however this is likely still some month off.
All the usual binary packages and source tarballs are available for download. As something new, I now also made apt-enabled repositories available for Debian and Ubuntu; this should greatly simplify installation on these

Percona Server version 5.1.50-rel12.1 RC is now available for download.
Dear Community,
Starting with this release, we introduce a new release model for Percona Server. From now on, we will have both Stable and Release Candidate releases. Release Candidates will introduce new features not yet available in Stable releases.
Along with new features, our new 5.1.49-12.0 RC contains a couple of patches from the Facebook-MySQL tree - https://launchpad.net/mysqlatfacebook . Of particular note is better integration with FlashCache.
We also introduce the very interesting new feature called ”Permanent InnoDB Buffer Pool” (sponsored by a Well Known Social Network site). It allows you to keep the InnoDB buffer pool in memory between restarts of MySQL servers.
This can result in a significant decrease in warmup time after MySQL restarts.
