Hi there,
I'm already applying Slony-I in a small single-master / single-slave
application test environment (non-commercial) and I have some question
considering the applicability of Slony-I / Slony-II in some more general
situations.

These questions are:

Ability to provide WAN replication.
 - Is it possible to use Slony-I in wide-are network (WAN) enviroment ?
The bandwidth on the master-master link is 34 Mbit/sec, on the
master-slave link 10 MBit/sec. Both sides will have a latency of 30msec.

Robustness concerning network drop out.
 - Can (slave) nodes which are not continuosly connected to network be
used ?

Satellite Connection. This scenario considers the replication between
master and slave nodes communicating over satellite.
 - Is Slony (-I, maybe the sucessor -II) capable for Replication over
satellite network (latency 850msec, bandwith 2 MBit/sec) ?

Data consistency. In this scenario, the two master nodes are
unconnected, changes are made and new primary-key values are generated
at both sites.
 - How will the upcoming Slony-II act by time the master nodes are
reconnected ? How about conflict resolution in the case of newly
introduced, equal PK-values at each (unconneted) site ? Is there any
design proposal ?

I'd like to appreciate any response to my open questions.

Thank you very much,
 Martin
