Thanks a lot for sharing this very valuable experience from the
field. However .setMaxRows() IS currently part of this portable and
severely restricted JDBC performance feature set, so I see no reason
for not trying to implement it as best as possible.

The more performance you can get from JDBC, the less not portable code
people will write.

And JDBC is evolving too.
