Thank you for such a quick answer, it's nice to know there is someone to
In posted question I indeed didn't exactly clarifiy what (probably) is
so special about these (and others) libraries, so let me do it now.
1. LMAX Disruptor architecture is desribed in Martin Fowler's article
here (long) - http://martinfowler.com/articles/lmax.html?t=1319912579 .
I got interested in it when I found it's being advertised as a "High
Performance Inter-Thread Messaging Library" by which you can run huge
number of concurrent tasks with minimal latency between each "thread"
(nanoseconds order of magnitude). Of course, it's not "that simple" but
still, the numbers are really amazing.
2. Java Chronicle library
(https://github.com/peter-lawrey/Java-Chronicle) which describes itself
as a "ultra low latency, high throughput, persisted, messaging and event
driven in memory database". With their numbers (16 nano-seconds latency
and throughputs of 5-20 million messages/record updates per second) I
think oi could be easily used as a platform to build very low-latency
message-queue or similar kind of middleware.
3. The well-known (it was mentioned on Erlang Factory) library Akka
(http://akka.io/) which copies actor model, distribution and
fault-tolerance from Erlang and again, looking at their numbers, tends
to be faster than Erlang in terms of message passing latency (due to
4. Kilim library (http://www.malhar.net/sriram/kilim/) which is somehow
similar to akka, but just for message passing. Anyway, similar strength
of zero-copy messaging.
And probably more, but that's what I remember the most.
One other thing is, that could be controversial, arising of Clojure
(mainly it, but also other FP languages on JVM) which show that we could
be faster just because of the Hot-Spot JIT compiler on JVM.
Of course, I could be all wrong, just because I'm rather a beginner
(still) in terms of functional programming, Erlang, etc. But I wanted to
know your opinion on the subject and maybe show me errors in the way I
see this problem.
