Things have been quiet for some time, but lots of things have actually happened.
I found an excellent beta tester in Rudolph van Graan of Patternmatched Technologies.
Rudolph has patiently waded through rdbms bugs, written test suites and excercised the code in quite demanding settings. From what I gather, things are now working quite well, and especially the ordered_set indexes of rdbms can prove to be a real performance booster.
We have yet to consolidate patches, but if anyone out there is interested in giving rdbms a spin, please know that you can get your hands on a much better version than the published one, if you only make yourself known.
Personally, I’ve been side-tracked in several ways. I picked up and moved to another city (Örebro), and started a new exciting programming project together with Joe Armstrong – the tuple store (we should announce a naming contest to find a better name…) We will continue to work on that in secret a while longer, until we have something that holds together well enough to show the rest of you.
