New features for Planet MySQL.

Lenz has opened a new section for Italian blogs (I should say blogs in Italian, since there are blogs that are hard to classify).

Thanks, Lenz. We'll try to fill it with some good contents.

In the meantime, Dups was creating a new feature for the Planet. MySQL Buzz is a window on living contents about MySQL, from forums to blog posts, to news and videos.

We released  ZRM for MySQL 2.1 Community Edition  today.  ZRM 2.1 includes the ability to treat snapshots as backup images. ZRM has supported backup of MySQL databases using storage snapshots using a plugin interface.  LVM (Logical Volume Manager) and Solaris ZFS snapshots are supported plugins in the ZRM Community Edition.
MySQL administrator can perform regular backups (backup images are stored in the ZRM server) or quick backups (snapshots acting as backup images). Quick backups have smaller backup windows and do not consume network bandwidth.  When MySQL database is stored on one or more ZFS filesystems, users can do multiple quick backups in a day (even once every hour) and convert one quick backup image to a …

Just got the news that our talk at the MySQL 2009 User's Conference has been accepted. Here's the abstract.

In this session we’ll be building a PHP+MySQL application that uses the Twitter API and has some AJAX fun with it.

You’ll also get a chance to see what it’s like to build an application in a PHP IDE like NetBeans. Those of you who use ‘vi’ might want to see how the other half lives, and scoff at us under your breath. Or you may actually get turned on to the power of a good IDE and realize hey, I could use some of that.

In this session we will be demonstrating

• Building a PHP+MySQL+web services+AJAX application in NetBeans
• Using the Twitter search API
• Using AJAX-based graphing tools to provide dynamic graphing to your application

The presenters are Justin Bolter, …

In past few quarters Zmanda has been growing at a break-neck pace. This has transformed us in many different ways. In the past 12 months, we have almost quadrupled our customer base (which is now in 40 countries!), introduced our third product line (Zmanda Internet Backup) and built new relationships with some of the leading IT infrastructure providers in the world.

These changes merit a fresh introduction. Some of you have openly wondered about who we are. Well, here is your chance to hear directly from us. Join us for a webinar on December 17th at 10AM (Pacific Time), titled: …

Rick Deckard is an Engineering Manager at MySQL. Rick is one of the most senior engineers in the company, he led the team during the long delivery of the newest GA version of the server, 5.1.

Soon after the release of 5.1, the Internet Village experienced shocking hours. A wind of disappointment spread all over the Net, blown by news of serious issues that affected 5.1. Many users were concerned, they feared for their mission critical applications based on 5.1, although they had already been in production for months without a glitch.

With great disappointment, the Net pointed the finger at Rick, asking for a clarification on these serious issues. "Is that so?" was all he would say.

After a few days, some wise users spent time reviewing the issues that affected 5.1. They discovered that some issues were not different by the ones that were affecting 5.0, and that version was currently in production. The …

FYI, we've now added an Italian section on Planet MySQL: http://it.planetmysql.org

If you are a MySQL enthusiast from Italy and would like to start blogging about it in your native language, please consider submitting your feed for inclusion!

Giuseppe just recently started blogging in Italian as well and has already added his feed there.

As usual, a very interesting blog from the CTO of GigaSpaces.With the graph above we see that the IMDG [In-Memory Data Grid, which runs on top of MySQL] scales very close theoretical linear scalability. The above results were achieved with an IMDG running on 2 partitions. Better scalability can be achieved by increasing the number of partitions.

Read more about how to scale-out the data-tier in Scaling-out MySQL.

To enable this level of on-demand scalability we used our new Cloud Framework, which combines the GigaSpaces SLA-driven container as the application deployment virtualization layer, Amazon EC2 as the machine level virtualization layer, and the GigaSpaces application server as the middleware virtualization layer. This way we can provision new machines as soon as the SLA on the web-tier is breached (measuring latency, in …

As discussed previously in Options using MySQL pairs I have started evaluating the strengths and weaknesses of various open source options. This is an evaluation of Flipper, a product from Proven Scaling a MySQL consulting organization.

Overall

• Pros When correctly configured and with a working installation it just works, simple and functional, which is good design.
• Cons The functionality is incomplete especially when it comes to edge cases, additional manual scripting especially for MySQL specifics is necessary and could have be easily added.
