OK, it's now official. See
for the InfoWorld articles on Rete-NT, the fastest rulebase on earth. The first is the Developer World article and the second is the InfoWorld Blog article. And, here's the really cool part; it's customer driven, everyone gets the same low-ball price ($5K / cpu / year) and any vendor that uses the Rete Algorithm in any form can add it to their engine with the help of Dr. Forgy. If the vendor doesn't want to hire Dr. Forgy, then they can hire whomever they like - but since millions of dineros will be depending on this, I think that I would want the inventor himself to oversee the integration of the Rete-NT into my product. Also, Rete-NT, like all of the PST products before, comes with it's own rulebase language called OPSJ - very similar to JRules and Drools language but a bit more powerful. BTW, the engine itself takes only 100K of RAM.
Dr. Forgy will be at Rules Fest 2010 in San Jose to answer any questions you might have but Rete-NT is proprietary to Production Systems Technology (PST). You might say that this is like the Borland Turbo-C/C++ when they charged only $50 for a better product than other vendors were selling for anywhere from $1,000 (M/S) to $5,000 (IBM) or something like that. That made the C/C++ IDE available to every college student in the world.
Think about it. A corporation could buy the Rete-NT for their servers and improve performance by 100 times or more in some cases, by only 10 times in the worst cases. When you are processing millions of transactions per minute (or even per second) you need the very fastest thing that you can get; and Rete-NT is it.
