[infinispan-dev] Improving Infinispan's Scalability: A new approach to group communication

[Radim Vansa]

Thanks for sharing the recording. Finally I've found out what's the 
purpose of total order protocol, although the drawbacks with WSC look 
pretty limiting. I'd really like to see the impact with WSC on, but that 
would require Infinispan itself as the main problem TOA is trying to 
solve is degraded performance due to deadlocking.

My main questions is about the ordering box size - if I understand that 
correctly, the ordering box consists of several physical machines.Then, 
what's the way to get the synchronized GSN from them? Is this the same 
as with regular TOA, taking the highest timestamp from all of the nodes? 
Or is there any internal synchronization within the ordering box?

Anyway, I like the idea of centralizing things, as the problem itself is 
centralized. And as my parallel systems teacher said, solving 
centralized problem in distributed fashion usually causes more trouble 
than it's worth.
