dear community,
I would like to implement global configuration replication for a cloud =
service.
the customer can update its service configuration at any site and =
changes are replicated worldwide.
eg.
main CouchDB sites in
- USA
- Europe
- Asia
main sites are full-mesh connected OR connected like a backbone ( =
USA---Europe---Asia ) always with bi-directional replication between =
main sites.
sub sites in each region are connected in a =82LDAP tree=91 way which =
connects to main site in the region.
eg:
- Western Europe will do a bi-directional replication to Europe node =
only
- France node will do a bi-directional replication to Western Europe =
node only
- Germany node will do a bi-directional replication to Western Europe =
node only
- and so on =85
this would mean a 3-layered approach down to each country node
a fourth layer may consist of different towns in the county
eg:
- Frankfurt node will do a bi-directional replication to Germany node =
only
- Berlin node will do a bi-directional replication to Germany node only

any way to do such a structure with CouchDB?
anyone already using such a strucure?
is it possible to connect 200 servers this way (globally)?
any ideas about replication time to expect in such a configuration (if =
possible at all=85)?
are there tools which are better suited to implement my needs?

hope this is not too crazy of an idea :)
kind regards
