restrict mysql replication ?

I have a need to have a number of small tables (perhaps up to 10000 row=
s
each) replicated to a number of mysql slaves. Frequency of change is
very low, and they need not be replicated within seconds, an hour is
fine. The master server has a lot more and bigger tables, but each
slave will only have a small subset of those. I've held off setting up=

proper replication, thinking it was too much effort, but I've now just
yesterday set up one such replication.=20

I've got the slave only replicating two tiny, mostly static tables, so =
I
had kind of expected not to see a lot of network traffic. Instead I
see lots and lots of replication traffic? I'm guessing the master
notifies the slave(s) of all changes, not just changes to the
replicated tables?=20

Is there a way of limiting that? Alternatively, is there a way of
doing "replication-on-demand", perhaps triggered by cron? =20

Ignore this, problem solved. I'll let the slaves query the master
regularly and just reload the entire table.=20

That works. As for what you're seeing, you're probably limiting replication
on the slave instead of limiting binlogging on the master. Can't quite
recall the exact option, something like binlog-do-db I think.

Yes, that sounds like what I'm doing.=20

Thanks for the hint, might still come in useful.
