Folks,
This is a broader question, but maybe somebody can help. I've set up a
simple WFS based on GDAL with Perl bindings. The service loads a dataset
from PostGIS copies it into a GML dataset in memory and serves it from
there.
Instead of storing a GML dataset in memory, it might help to pipe it directly
to standard output (using /vsistdout/ filename). That should consume very few
memory.
A good idea. The only issue I can think of is that it might be a good
idea to tell the client the size of the GML dataset and that's not known
beforehand. I'll make some tests with that.
I guess I could also try to catch out-of-memory errors happening in GDAL
by wrapping them with Perl eval and then bailing out more gracefully.
Cheers,
Ari
