Hi Nyall,
>> and dissolving by "distrito" the ogr2ogr based tool is 2/3 seconds >> faster than the new native one. > > For comparison, how long did each take in total? about ~28/29 seconds ogr and ~ 31/32 native (on a testing VM with limited resources). > Hmm - works fine here. Can you try turning off the invalid geometry > checking in processing options? That's a little broken at the moment > (with the error you've noted below) if I turn off that option then it works, both dissolving by attribute and a full dissolve. The speed difference is not much (ogr always a bit faster in my testing environment). > Outdated message ;) It's refering to the option in processing settings. yes, i realized it later. > That should be really straightforward to add to the feature iterators > now. But alternatively there's a processing alg which repairs > geometries too (not in master yet, but in earlier 3.0 builds). both very good news! but don't forget that in the economy of a work day of a person that do all day this kind of operations, having an option to fix geometries on the fly while clipping/intersecting/etc is very important and save a lot of time. Of course having the same functionality as separate tool is as much as important. cheers! -- g -- _______________________________________________ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
