This was pointed out to me today: http://kafka.apache.org/
I can't help thinking that kafka + AwDb > Datomic
Any interested parties?
What if we did it using Clojure?

well if you make a quick stab at it and then post on the clojure list, you could well get some traction!

I already got my post to the datomic group skuttled by the monitor. :-(

?! lame !!! well post to clojure instead as soon as you have a small integration demo.

Oh. an integration demo.
I'm tied up right now finishing up the role based access control system. Deploying it in the front end will take a few days and it is too hot to work.
More excuses available on request. You are taking me out of my comfort zone. :-(

this is surprising to me considering all you have accomplished to date :-)
slapping together some jars and writing a main() routine to do a single write-read should be enough to start?

I mean, we are talking about splitting AwDb into 3 parts to recreate the Datomic architecture. Not a small thing.

i would say just do whatever evil hack you can as a demo/poc. make everything public, whatever! then call into the innards! whatever! just make something that actually frobs some data :-)

Question for you Raoul. https://github.com/tonsky/datascript
It says it is a closure datalog that runs in the browser. But it is closure, right? So it could be adopted to run on top of AwDb?
AwDb has an object store on top, while Datomic provides datalog. Just wondering if AwDb could also provide a datalog implementation.

clojurescript is supposedly raw clojure that just happens to compile
though to javascript. So in theory the same source code is regular
clojure and can be compiled to the jvm instead.
but! if a given clojurescript project links to other javascript libs,
then it can't be used on the jvm i should think.

I have been reading this one and I see the Datalog mentioned here

"Although not used commercially
at present, Datalog has been used in several research database systems."
I suspect Datomic is not the only commercial use of Datalog. Times change. And there is a growing effort to use the semantic web, which some implementations of datalog support. (But not, apparently, the Datomic version.)
