Dear Andreas

We have around 15-20 big table tables, each has around more than 2000
rows in that tables.We need to set any parameter in postgresql.conf file
or 
Parameter needs to set for the slony.


Best regards,

g.Muniswamy

Subject: Re: [Slony1-general] Slave system becomes Slow

Just out of curiosity, how many rows are touched by the updates on the
master?

One important thing is:

select count(*) from tablea => 1000
update tablea set fieldb=fieldb + 1 => 1 update statement on master,
                                    => BUT 1000 updates on slave

So it's easy to overwhelm a slony system with one statement that
touches many rows.

Andreas
