So if I understand you, you have an attribute index implementation available that we could use to optimize shapefile access.
Can these indexes be used with qnx index (like can we use both at once?). So yeah I like this idea very much, to formally propose a new feature like this we ask people to create a wiki page (see our developers guide for details <http://docs.geotools.org/latest/developer/procedures/proposal.html>). There are examples here <https://github.com/geotools/geotools/wiki/Proposals>. -- Jody Garnett On 5 November 2015 at 13:06, A Huarte <[email protected]> wrote: > Hi, I would present for review or opinions, a new Dbase index classes-set > to speedup alphanumeric queries in shapefiles. > > > https://github.com/geotools/geotools/compare/master...ahuarte47:GEOS-6842_CdxDbaseIndex > > Now, for no-spatial nor fid-index queries, the shapefile reads all > features to evaluate the filter.
