Hibernate OGM: birth announcement

From the post:

This is a pretty exciting moment, the first public alpha release of a brand new project: Hibernate OGM. Hibernate OGM stands for Object Grid Mapping and its goal is to offer a full-fledged JPA engine storing data into NoSQL stores. This is a rather long blog entry so I’ve split it into distinct sections from goals to technical detail to future.

Note that I say it’s the first public alpha because the JBoss World Keynote 2011 was powered by Hibernate OGM Alpha 1. Yes it was 100% live and nothing was faked, No it did not crash ­čÖé Sanne explained in more detail how we used Hibernate OGM in the demo. This blog entry is about Hibernate OGM itself and how it works.

Congratulations!

JBoss World 2011 keynote demo

From the webpage:

Visualizing data structures is not easy, and I’m confident that a great deal of success of the exceptionally well received demo we presented at the JBoss World 2011 keynote originated from the nice web UIs projected on the multiple big screens. These web applications were effectively visualizing the tweets flowing, the voted hashtags highlighted in the tagcloud, and the animated Infinispan grid while the nodes were dancing on an ideal hashweel visualizing the data distribution among the nodes.

So I bet that everybody in the room got a clear picture of the fact that the data was stored in Infinispan, and by live unplugging a random server everybody could see the data reorganize itself, making it seem a simple and natural way to process huge amounts of data. Not all technical details were explained, so in this and the following post we’re going to detail what you did not see: how was the data stored, how could Drools filter the data, how could all visualizations load the grid stored data, and still be developed in record time?

If you follow the link to the video, go to minute 41 for the start. Truly a demo worth watching.

This blog post gives the details behind the demo you see in the video.
