It should support a large number, but it depends on the work load, e.g. number of syncs, number of rows changed, etc. Best way is to test your situation and see. > Where can I find any documentation/links regarding bucardo performance? It's asynchronous, so we don't worry too much about copy speed, although taking more than a second or two to propagate out is unusual. The big overhead comes from the use of triggers on the affected tables. I've heard figures from 1 to 10% thrown around, but (again) the best way is to measure your own system. If there is a particular peerormance concern, you can email this list. > 2) What are the minimum requirements of bucardo installation on a slave node? > > For example, do I need to compile Postgres with Perl support on a slave node? The only requirement is that you have a recent enough version of Postgres (8.4 I think), and a superuser (e.g. bucardo) that can connect to the database. -- Greg Sabino Mullane [email protected] End Point Corporation PGP Key: 0x14964AC8
