[Gluster-devel] Replicate/AFR Using Broadcast/Multicast?

[Craig Carl]

Gordon - 
PGM is still experimental so it will be a while before we would consider implementing it, I would also expect to see network issues as a cluster grows. It would also limit a Gluster cluster to a single broadcast domain. We would have to find a way to manage these challenges, do you have any thoughts? 



Thanks, 

Craig

Subject: [Gluster-devel] Replicate/AFR Using Broadcast/Multicast? 

Are there any plans to implement Replicate/AFR using broadcasts (on a 
LAN) or multicast? At the moment, write performance scales inversely 
linearly (O(n)) as additional nodes are added, which gets in the way of 
scalability. It'd be really useful if this could be done using reliable 
multicast (e.g. PGM), as the scaling wouldn't be inverse (it would go to 
O(1)). Are there any plans in this direction?
