I mean, all the filtering and calculations could be done in my SVG
Renderer in Geoserver but I think it would be much faster within
the database.
Agreed... but getting GeoServer to serve that out will be tricky...
I am afraid you are right. I saw that Andrea is one of the geotools
postig classes devoloper. Maybe he has an idea?
am I right that until
Query bboxQuery = new DefaultQuery(schema.getTypeName(), bboxFilter);
Query definitionQuery = layer.getQuery();
DefaultQuery finalQuery = new
DefaultQuery(DataUtilities.mixQueries(definitionQuery, bboxQuery,
"svgEncoder"));
finalQuery.setHints(definitionQuery.getHints());
finalQuery.setSortBy(definitionQuery.getSortBy());
finalQuery.setStartIndex(definitionQuery.getStartIndex());
featureReader = fSource.getFeatures(finalQuery).features();
until the last line is executed in my SVGRenderer or in any other
Renderer the database is not queried?
Wouldn't it be useful (i am asking in general) if a PostGIS would
somehow also promote functions that have a geometry column, just like
having a geometry_column table you would have a geometry_funcion table
which also includes the desired paramters...if any? Just an idea from
a total newbie to all this...
Thanks
