In response to a number of comments, I thought I would clarify the scope of my discussion regarding Options using MySQL pairs before I begin. As mentioned their is no one way or type of configuration for MySQL in a HA solution, however the simplest progression from a single Master/Slave environment is the concept of a pair of servers, configured to support a fail over and fail back via MySQL Replication.

The concept of a MySQL Pair in this context is to have a “hot” MySQL standby ready for controlled and hopefully! automated fail over. I say hopefully because with MySQL Replication as an asynchronous solution there is no guarantee for no loss of data.

I consider DRBD/Heatbeat for example a “cold” standby, as MySQL on the slave server is not actually running. DRBD does provide …

When Monty Widenius published his criticisms of MySQL 5.1 recently a lot of the coverage that followed focused on his belief that the product had been made generally available too early and has too many serious bugs.

A solution to this problem would have been told hold 5.1 back even longer for more testing or, better still, not to have announced it as a release candidate so early. However, reading Monty’s post in full indicates that this would be a matter of treating the symptoms rather than finding a cure.

He also wrote: “the MySQL current development model doesn’t in practice allow the MySQL community to participate in the development of the MySQL server” and “I think it’s time to seriously review how the MySQL server is being developed and change the development model to be more like Drizzle and …

The FOSDEM 2009 organizers have been very kind to us this year: in addition to a Developer Room on Sunday, we now also have a project desk (1 table) on both days! Thank you very much! In summary, this means that there will be the following MySQL-related activities:

• We will have a Project Stand (one table) on both days
• On Sunday, we will have a MySQL Developer Room, allowing us to schedule our own track of talks about MySQL and related projects
• I have been invited to give a talk about "MySQL High Availability Solutions" in the main conference track
• I also submitted two proposals for lightning talks ("What's new in MySQL 5.1" and "Why you should use Bazaar for maintaining your OSS …

My CAOS colleague Matt Aslett wrote recently about how we expect to see an uptick in open source merger and acquisition activity given the current economic conditions and bargains for the larger, mostly proprietary players. Matt also discusses the difficulty of further VC funding, though we have seen some significant investment announcements, such as Open-Xchange, Infobright and others. Still, Matt is probably right that funding will be harder to come by for any company, open source or not.

I also continue to see a number of startup and younger open source vendors — would-be fundees — that are opting to hold off on venture funding and stick to building up business, customers and …

I just noticed that Sun/MySQL has dropped SCO OpenServer from its list of supported operating systems for MySQL 5.1 and higher (along with Mac OS X 10.3 and QNX).

It is not a massive surprise to see MySQL doing this given SCO’s current position but MySQL teamed up with SCO in the midst of its controversial legal claims against IBM et al, so I thought the end of the deal warranted a quick mention.

At the time Marten Mickos defended the deal by claiming that he hoped working with MySQL would educate SCO’s executives:

“In a partnership you exchange thoughts,” he said. “If you exchange thoughts hopefully the other side will listen to you. We understand …

Some days ago, I released version 0.11 of mylvmbackup a Perl script that performs consistent backups of a MySQL server by using LVM filesystem snapshots. The source archive as well as a generic RPM can be found on the project home page, packages for many Linux distributions are available on the openSUSE Build service.

This release includes some new functionality as well as numerous bug fixes and improvements, most notably:

• Added support for using rsnap as a backup backend (Matt Lohier)
• The documentation is now maintained in POD style instead of asciidoc (Matthew Boehm)
• Support using non-GNU tar and …
