Hi Andrea,
I'm running Geoserver 2.9.0. If I cannot use "attribute in (list of
values)", is there another way of setting up such a filter which may be
more efficient?
Sincerely,
Eva

The query itself is quite slow (about 10 sec for 8000 ids), but
the main performance loss appears to be with Geoserver. I'm not
sure, but this seems to me an inefficient way to handle the
CQL_FILTER request.
The not null checks are redundant for sure, but there is no notion of
"att in (list of values)" in OGC filter, so we have nothing else to
translate into (e.g., we have
no way to represent it in our code, we'd have to go beyond the tools
that OGC provided us there, with some risk of becoming non compliant).
What version of GeoServer is that?
Cheers
Andrea
