Announcing Percona Server 5.6 Alpha by Stewart Smith

From the post:

We are very happy to announce our first alpha of Percona Server 5.6. Based on MySQL 5.6.5 and all the improvements contained within, this is the first step towards a full Percona Server 5.6 release.

Binaries are available to download from our downloads site here:

We will post binaries to our EXPERIMENTAL repositories later, we’re undergoing final testing to ensure that it won’t cause problems for those running Percona Server < 5.6 from EXPERIMENTAL. Percona Server 5.6.5-alpha60.0 does not contain all the features of Percona Server 5.5. We are going to “release early, release often” as we add features from Percona Server 5.5. As such, our documentation will not be complete for a little while yet and these release notes are currently the best source of information – please bear with us.

Go ahead, take a walk on the wild side! 😉

Percona Toolkit 2.1 with New Online Schema Change Tool

Percona Toolkit 2.1 with New Online Schema Change Tool by Baron Schwartz.

From the post:

I’m proud to announce the GA release of version 2.1 of Percona Toolkit. Percona Toolkit is the essential suite of administrative tools for MySQL.

With this release we introduce a new version of pt-online-schema-change, a tool that enables you to ALTER large tables with no blocking or downtime. As you know, MySQL locks tables for most ALTER operations, but pt-online-schema-change performs the ALTER without any locking. Client applications can continue reading and writing the table with no interruption.

With this new version of the tool, one of the most painful things anyone experiences with MySQL is significantly alleviated. If you’ve ever delayed a project’s schedule because the release involved an ALTER, which had to be scheduled in the dead of the night on Sunday, and required overtime and time off, you know what I mean. A schema migration is an instant blocker in the critical path of your project plan. No more!

Certainly a useful feature for MySQL users.

Not to mention being another step towards data models being a matter of how you choose to view the data for some particular purpose. Not quite there, yet, but that day is coming.

In a very real sense, the “normalization” of data and the data models we have built into SQL systems were compensation for the short-comings of our computing platforms. That we have continued to do so in the face of increases in computing resources that make it unnecessary, is evidence of short-comings on our part.

Percona Server 5.5.17-22.1 released

From the webpage:

Percona is glad to announce the release of Percona Server 5.5.17-22.1 on November 19th, 2011 (Downloads are available here and from the Percona Software Repositories).

Based on MySQL 5.5.17, including all the bug fixes in it, Percona Server 5.5.17-22.1 is now the current stable release in the 5.5 series. All of Percona ‘s software is open-source and free, all the details of the release can be found in the 5.5.17-22.1 milestone at Launchpad or in the Release Notes for 5.5.17-22.1 in the documentation.

I haven’t installed or run a Percona Server, but the reported performance numbers are good enough to merit a closer look.

If you have run a Percona server, please comment.
