Hi,
I have a master-slave model running just great.

I now want to replicate a subset of the above database to a number of 
other nodes.  I thought of replicating this from the aforementioned 
slave (to reduce the the load on the master).

The question is:  should all the nodes be one cluster ie master, slave 
and all subnodes, or should I have one cluster for the master-slave 
replication and one cluster for the slave-multinode replication.

I can't seem to find the policy/rules/conventions about cluster creation.

can any offer pointers or references....

Thanks
John
