![]() Idx_all.append(layer.fields().indexFromName(i)) #Filter Fields by selecting columns of interestįields = Layer = iface.addVectorLayer("name.gpgk]","name","ogr") This is my code: from re import QgsTrackedVectorLayerTools What I want to do is split the whole area in four parts, than for every tile I want remove to all fields where I'm not interested in and make some calculation on the remaining fields followed by a conversion to a raster. ![]() ![]() I thought about the implementation of parallel processing using all four cores, but I didn't find any helpful information. I am wondering how I can speed up processing. I wrote a small script in Python to delete uninteresting fields and perform calculations on the remaining fields of interest, but this process comes to no end. I am working on a big vector data set with more than 2.4 million features containing 10x10m squares.
