What shared state distributed systems exist which can handle objects in the native language?

Question

As far as I know there is Terracotta and Maglev. Are there any others?

Pretty much every big vendor got one, plus a handful of independent vendors:

memcached [1] — ubiquitous, community-driven;
Infinispan [2] — backed by JBoss, open-source;
Velocity [3] — commercial (Microsoft), in beta, .NET only;
Gemfire [4] — commercial (VMWare)
Coherence [5] — commercial (Oracle)
GigaSpaces XAP [6] — commercial
ScaleOut [7] — commercial
Terracotta [8] — commercial

Note that there is a pretty thin line between state sharing solutions and distributed caching solutions. I only listed the ones that keep the state in main memory, which are often dubbed "data grids" on the street.

Hope this helps.

memcache : many major sites use it, Google AppEngine included. There are bindings to it for everything under the sun (pretty much ;-)

My mistake, I worded the question badly, but you were right, memcached is a shared memory system :) – yazz.com Feb 18 '10 at 19:51

Memcached is probably the most heavily used one (as their biggest user Facebook shares 28TB of RAM with it at the moment).

I researched velocity, but it seems to be just a research lab project and not much info on it. Will it ever see the light of day? – yazz.com Feb 18 '10 at 20:12
Microsoft are promoting it, so guess so? – Oded Feb 18 '10 at 20:22
Ok, thanks. When I get time I'll download it and give it a try. – yazz.com Feb 19 '10 at 08:27

Since you mentioned MagLev, there's obviously also GemStone/S on top of which MagLev is built, and GemFire, their JVM/.NET/C++ product.
