we do millions of operations like the following
find_feature(latitude, longitude)
currently we basically call:
Filter filter =
filterFactory.insersect(geometryFactory.createPoint(latitude,longitude),
expr) ;
DefaultQuery query = new DefaultQuery(null, filter);
features = ustzFeatureSource.getFeatures(query);
for(Feature f : features) {
.....
}
but as the attached stack trace shows, every creation of the features
collection (i.e. corresponding to every query ) invokes
creation of a new featureReader, and opening of the index file, which
takes a lot of time.
since the dataSource never changes ( we always query against the same
shape file and index), is there a way to let geotools
use the same file channel ?
Thanks
