JavaOne wrapped up on Friday. We hosted individuals from across the globe, and from every industry: consumer electronics and gaming, to enterprise IT, space exploration, factory automation, the automotive industry, academia - like the network itself, Java delivers something for nearly everyone, everywhere.

This year's biggest announcements centered around Java's role in the future of rich internet applications (or RIA's). What's a rich internet application? It depends on your perspective - from mine, it's any network connected application that persists in front of a user, typically outside a browser, that can operate when disconnected from the network.

On the one hand, I'd claim Java's always been a RIA platform - before the world really wanted one. Early Java applets delivered interactivity, but at the expense of development complexity and, in the early days, performance - when a browser, and more recently Javascript, would …

I’m going to be migrating to using ZooKeeper within Spinn3r for a myriad of reasons but this one is especially powerful.

One could use ZooKeeper to configure external monitoring systems like Munin and Ganglia.

ZooKeeper enables this with its support for ephemeral files.

If you have an external process like a webserver, database, robot, etc you can have it create a ephemeral file which registers its services and presence in the cluster.

For example:

/services/www/www32.mydomain.com/80

Would represent a machine named www32.mydomain.com.

You can then have munin connect to ZooKeeper and enumerate files in /services/www and have a cron script continually …

First up, I want to say, I’m truly impressed with Brazil. One day I will visit this amazing place, and spread the good word of open source with projects that are close to my heart: MySQL, OpenOffice.org, Fedora, and in due time, a lot more. This is a live-blog, from a most interesting talk, at JavaOne 2008. As I wrote on Twitter, “Brazil, simply impresses me. Their use of open source in government, makes me think that the rest of the world has a lot to learn from them”.

When creating Visual JSF projects in NetBeans 6.0 (and 6.1) to connect to and execute database operations from a JSF application a data source is created by dragging and dropping a database table to the Design view and right on top of a JSF component.  This creates a JSF binding to the component.  By default the data source name generated is [schema name]_[database product name].  If you're using MySQL then the table name is used instead of the schema name.  To see the name generated for your database connection, for your project in the Projects window, expand the Data Source References node.

 If you want to choose the data source name generated then an option has been added.  Open the Options dialog from the Tools main menu.  Next click the Miscellaneous icon at the top and then click the Visual Web tab.  Next, check the Prompt for Data Source Name …

Just two weeks after having returned from the MySQL Conference, I just arrived safely in San Francisco again. This time to attend the CommunityOne on Monday and the JavaOne conference from Tuesday till Friday, which should keep me occupied for the rest of the week. I look forward to meeting my fellow MySQL team members (Colin, Giuseppe and Jay will be here, too), as well as many new colleagues from Sun! Shoot me an email, if you would like to meet.

After following the scale up path (i.e. buy bigger boxes) for a while now, we definitely need to scale out as things start to become “unhandy” and simply HUGE. (See small things are better)

We are running an OLTP application with about 200 million transaction per month. Currently we have some very large tables with more than 1,5 billion rows and the total database size is about 600 GB - all InnoDB.

What we want to implement is application based sharding, i.e. splitting up the big tables and distribute them among many smaller servers. Furthermore we need to implement some sort of archiving mechanism since the db size is growing very fast. Putting old data into compressed myisam tables seems to be a good solution here.

So, how to implement this?

These solutions come into mind immediately:

As Kaj already pointed out, the Sun/MySQL Meetup Mashup Tour will also make a stop in Munich, Germany this Friday. I will be there as well, we will meet at 14:00 at the Hilton Munich Park Hotel. Kaj and some other Sun people will join us a bit later. If you are in the area, make sure to stop by!

By the way, the Meetup Mashup Tour will make at least one more stop in Germany - I am organizing an event in Hamburg, Germany which will take place on Monday, April 7th (19:00). This was initially planned as another regular MySQL Meetup, but I offered to expand the scope a bit. We will now meet at the Sun offices, Sun will sponsor some food and drinks! In addition to …
