As burtonator pointed out parallelism is an important
feature that partitioning makes possible. So I thought
it might be a good idea to mention a little bit what
we're doing in the area of partitioning.
It's quite correct that parallelism is one of the main
advantages of partitioning (not the only one though since
also partition pruning and dividing large indexes and
being able to add and drop partitions efficiently are
important as well). In 5.1 we focused on the maintenance
features of partitioning but the intention to move on
to parallelisation was more or less the main goal from
the very start.
This is why it's such extra fun to actually get going on
this when one has worked on the foundation for this work
for almost 4 years (partitioning development started out
2004 H2 and most of the partitioning code in 5.1 was ready
about two …
It may be tested again! Reason for the new version are two new
releases of the main components of XAMPP: PHP and MySQL.
New in both XAMPP versions: MySQL (5.0.67), PHP (4.4.9), and
phpMyAdmin (2.11.8.1). .
Go to XAMPP BETA download area
XAMPP BETA versions are always for testing purposes only. There
will be no upgrade packages from and to beta versions. To all
testers: Many thanks in advance!!
Es darf wieder getestet werden, neue XAMPP-Betas sind da. Grund
sind zwei neue Versionen der Basiskomponenten MySQL und PHP, die
seit der letzten XAMPP-Version erschienen sind.
Neu in beiden XAMPP-Versionen: MySQL (5.0.67), PHP (4.4.9) und
phpMyAdmin (2.11.8.1).
Zum XAMPP-BETA-Bereich
Beta-Versionen sind ausschließlich zum Ausprobieren und Testen
da. Wir würden uns allerdings sehr freuen wenn ihr einen
kritischen Blick auf diese Version werfen könntet und uns
berichtet, ob die Beta bei euch problemlos lief oder sie Probleme
gemacht hat.
Baron posted something interesting about agent vs agent-less monitoring in response to Rob.
While reading it, I couldn’t help thinking that the distinction is somewhat misleading, if not wrong.
I’d go so far as to say that agent-less doesn’t exist as such. Why do I say such heresy?
Trivially, you need some piece of software to collect data. With munin you configure a server that triggers scripts on the monitored servers. The set of data sources is governed by what you install in the correct directory on the monitored server. Cacti relies on SNMP heavily and also …
[Read more]“MySQL Cluster 6.4 Windows tree” branch in Launchpad
That’s right folks, I’m pushing up patches for MySQL Cluster on Windows. This tree is incomplete, and no promises on when enough will be pushed for it to even compile on Windows.
Tree is updated when launchpad pulls from our internal tree.
Last week I gave my first webinar for MySQL titled “Bau sicherer LAMP Anwendungen”. The webinar, which was a cooperation between MySQL and my company SektionEins, was held in german, covered SQL-Malware, SQL-Injection, safe programming and some tools to detect and block SQL-Injection attacks.
The recording of this webinar is now available on the MySQL site.
For those that only want to see my slides they are available on the MySQL site after registration or here.
Because it was a german webinar the recording and slides are in german, too.
I’ve been following the Drizzle project with some interest. There’s a lot to like about it. But you know what I like most about the project?
No dual licensing. Just plain GPL, version 2.
I personally think this is the foundation for why people are empowered, why there is excitement, why there is progress, [...]
Rob Young has posted a few blog entries lately on the MySQL Enterprise monitoring software. His latest post claims that agent-based monitoring is equivalent to extensibility (MySQL Enterprise Monitor: Agent = Extensibility).
I think this is conflating two completely distinct properties of a monitoring solution. Cacti is extremely extensible, with a plugin-based architecture and [...]
An interesting article on Facebook, Which deals with MySQL's replication system, Memcache and the replication delay.
... by setting a cookie in your browser with the current time whenever you write something to our databases. The load balancer also looks for that cookie and, if it notices that you wrote something within 20 seconds, will unconditionally send you to California. Then when 20 seconds have passed and we're certain the data has replicated to Virginia, we'll allow you to go back for safe pages.
