The major point Jan brings up when you talk about this is that
eRServer offers a nice failover model. But then what? How do you get
back to your production server? Swapping master/slave to do
maintenance on the master using eRServer is not really something a
mere mortal can do, either. I paid for a license to use eRServer. I
wouldn't ever do that again... It was unable to solve my main problem
with multi-million row tables, but it did work on a small production
database with a few hundred rows just fine (albeit with 200MB+ memory
footprint!)
