Multi master greater than 2

Hi,

I'm develping an application which centres around replication, with each replicated node also being written to by the application, requiring multi-master type replication.

I've been investigating MySQL replication for this. Using 5.0.18, I've set-up a "ring" network of MySQL servers, each node communicating with each other node. This works great.

Since this requires an unbroken ring to work properly, I'd like to set-up replication in a star topology, with each node replicating to a central hub. Hub to end point is standard two-way replication. However, hub to end node requires multiple MASTER definitions on the hub. MySQL replication should, in principle, support this, I would have thought, however the CHANGE MASTER TO syntax does not.

Does anyone know if this is possible?

I'm using auto_increment_increment, and auto_increment_offset to ensure all the 'masters' row uniqueness.

Best regards,

Robert
