Hello,
 =

I had hoped one of you could answer a query about Slony-I's functionality. =

 =

I propose creating what is a multi-master replication set in an extremely l=
imited sense. The master is where data about items in stock and their detai=
ls are stored. The slaves have no cause to modify these tables, but require=
 their own local copies, which they acquire through replication. However, t=
he nodes need to report some things back to the master (which is where the =
core business logic is implemented), where they may have there own table(s)=
 that accrue information given by the slaves (sales information). So, there=
 are different masters, but each is a master only in respect of its own tab=
les (replication set).
 =

The question is, can I use slony-I in this way to retrieve this information=
 from the slaves, or will I need to devise another mechanism, such as accru=
eing sales as XML or something, and sending them via some generic messaging=
 protocol (the system is implemented in C++) ?,
 =

Regards,
Peter Geoghegan
