Billy Newport, myself and the rest of the eXtreme Scale crew were lucky
enough to attend QCon in San Francisco a few months ago. They've been
posting the presentations online, and recently Billy's talk about key/value
scalability and our Chirp demo was posted. Interesting stuff.. especially
the questions it brought up and the extra ideas we were able to come together
on. Great conference with great technical minds in attendance.

A week or two ago, Billy Newport published some sample code for a java-based
bloom filter, citing quite a few reasons why elastic data grids and bloom
filters are complimentary. You can read more detail in his blog post, but
in essence a bloom filter is an extremely space-efficient method of keeping
track of membership of an object in a large list of objects. At its core, a
bloom filter can tell you if an object is definitely NOT in a list, and with
some predictable probability whether or not it is. They work great for
scenarios where most of the time you're going to expect an... (more)
So Sun and Oracle are officially going to be one company. It affects my
daily life in some interesting ways, but as a Technical Evangelist for IBM
that's to be expected. Both of these companies have been at the center of
my 'coopetitive' world for years now. From industry organizations to
strategy sessions and relationships with competitive friends/allies, I have
to change my routine. However, does this have an effect on the direction of
enterprise development, or the raw materials available to us to solve our
business problems? I really don't think so. I'll say why but it'... (more)
I thought it would be a good idea to call some attention to a new flood of
good reads added to the collection of white papers focused on WebSphere and
JEE software. Two in particular deal with some bleeding edge performance
concepts. Performance is a subject that comes to the forefront more and more
often, especially when we're all trying to wring as much sweat as we can out
of each and every IT dollar put into play. Much of my day is spent trying to
find new patterns to make this a reality. Information like this is invaluable
when we're trying to find the correct architectural a... (more)
So we've got this little mantra that we've used to distill a lot of our XTP
(eXtreme Transaction Processing) concepts down to a core message.
"Predictable Scaling at a Predictable Cost"
It's not as catchy as "Just do it", but we like it. I think it's important
to make it clear what we mean when we say it, however, and it really comes
down to the real benefits attained with XTP applications built on top of XTP
products. We're not just talking about ridiculously high loads when we try
to architect a scalable solution. There are only so many Facebook's and
Twitters that need to s... (more)
