I agree that would be the perfect solution… unfortunately it is not the way
works today ☹
No dirty workaround ? damned…

Hello,
We have geoserver based WMS services that display a quite large network (lots
of points and polylines stored in an Oracle Spatial database).
When in the cities, the number of items can be very large
In the countryside, of course, the density of polylines is quite low.
If I try to render a whole city, since there are too many items to render, the
request will timeout.
You can increase the max rendering time in the WMS panel
But if I set a scale condition to avoid drawing thousands of lines when in a
large city, users complain that they can’t find the cables when in the
countryside…
So my question was : is there a way to tell geoserver to render a blank image
if there are more than n items in the Oracle resultset ?
That way, I could keep a large scale in my TLD without going timeout in areas
where there is a high density of items.
No, there is no such functionality. It is of course possible to add it, but
we'd need to make
an extension to SLD, the limit would have to be specified at the
FeatureTypeStyle or Rule levels
Cheers
Andrea
