That seems like a very complex situation, that is not
straight-forward, mainly because of the node count. Erlang by
default creates a fully connected network topology when using the
distributed Erlang. That generally means that Erlang clusters using
distributed Erlang should be limited to roughly a hundred nodes
unless some type of hierarchy (tree) of nodes is used. To do a
hierarchical setup seems like it would be more difficult than with
other systems, and I have not seen a good example or research in
this area, as it relates to Erlang. If you got a hierarchy working,
then you could use hundreds of nodes, and try to get mnesia
replication working with updates propagating the network. This task
sounds like it might be a better fit for something like Riak or
Scalaris.<br>

Hi all,<br>
<br>
Is it possible to setup a Mnesia cluster consisting hundreds (or
more) nodes, wherein each table is replicated by 3-4 nodes? I
think the problem may be concerning Mnesia schema, which is shared
by the whole cluster, and tables are dynamically created, deleted
and moved. So I worry about the schema_transaction overhead.<br>
<br>
Best regards.<br>
