When using the GeoTools tutorial sample to display a map, modified for
DB2, the query generated creates a filter a little greater than the data
bounding box. This is time-consuming to process, checking if each
feature is within the query area where a straight table-scan of all the
data would be much much faster. When the DB2 filter code gets control,
it doesn't have access to the data bounding box in order to change the
behavior, as far as I can tell.
Is this behavior expected?
