I came across an article discussing NoSQL and partition tolerance.
The NoSQL Partition Tolerance Myth (link)
I may not entirely agree with the author.
But what most NoSQL systems offer is a peculiar behavior that is not
partition tolerant, but partition oblivious instead.
No argument here. While NoSQL implementations are aware that nodes have left,
they are not aware that said nodes have formed a separate partition.
In this case, we would want failure detection and carry out those transfers
where the accounts are both on the same side of the partition, while denying
or deferring transfers that cross the chasm.
The author is assuming that the account is only on one side of the partition.
If that is that is case, is doesn’t matter whether the NoSQL implementation
is eventually consistent or not. If the account is on both sides of the
partition, the solution the author... (more)
2013 middleware predictions by Red Hat's Craig Muzilla. This post originally
appeared on Dec. 18, 2012.
Last year, I offered my thoughts on trends and developments that the market
would see in 2012. At that time, I felt that we were looking at a continued
emphasis on cloud, while mobile and backend integration technologies would
rise in prominence within enterprise IT. I think the industry made progress
in all three areas: analysts indicate huge adoption of mobile technologies as
a substitute for what would have typically been a laptop or desktop computer;
at Red Hat we saw an u... (more)
In Madrid, Paris, Munich, Zurich and Geneva we are presenting at JBoss
Forums, talking about the product portfolio and zooming in to the JBoss
Business Rules Management System (BRMS).
I took the time to demo several of our integration products, both BRMS and
the SOA platform as they leverage rules, bpel, bpm and complex event
processing. The demo projects are freely available online so that you too can
rock your own JBoss sessions!
The original Home Mortgage Demo project started out with Red Hat JBoss SOA
Platform (SOA-P) and Red Hat JBoss Business Rules Management System (BRMS) to
integrate rules, services, ESB, and BPEL orchestration to pre-qualify home
loan requests. In later versions we took this demo project forward with the
more recent versions of both JBoss SOA-P and JBoss BRMS, but the final step
was to leverage the existing components, such as the decision services and
the BPEL orchestration services.
Part I – introduction and project setup
We walk you through the setup and contents of the Red Hat... (more)
Last October I published a post that identified the features that both JBoss
Data Grid and Oracle Coherence provide (link). My goal was to establish a
baseline for the features that a data grid should provide. It was not to
state that one data grid was better than the other. Little did I know an
Oracle employee would respond by attacking Red Hat, its engineers, and
It is fear? Is it hostility? I don’t know.

a competitive discussion in response to one of my posts comparing IBM
