Hi,

I'm a newbie to slony1 as well, but it seems to me that it's designed
more for a round-robin type clustering system than beowulf-type
clustering. That is, each system replicates the entire database on its
local storage rather than handling a small part of larger queries that
are spread over the whole cluster, and all the hosts are read-only.

The tablespaces functionality in Postgresql 8 by Fujitsu may be a step
towards what you're looking for - it allows for different tables to
reside on separate file-systems or hosts and be transferred amongst
these different locations without interrupting service.

One thing I would suggest to get clustering-type effects is that you
have INSERTs/UPDATEs only go to the master host, but queries are
round-robined. Writes are generally much more rare than reads, so this
allows you to have the load-balancing of a cluster without the expense
of Oracle ;-)

Regards,
Dan
