I am quite new to the use of ArcPy but am using it instead of ArcGIS Modelbuilder as I thought it might speed up my workflow. I have a large set of polygon features in a geodatabase (around 12.000), which I want to merge/append into one single feature layer. columnnames and data types are all the same for each file.
My script is working, but my problem is that the processing seems to gradually go slower and after around 2000 features really takes a while before moving forward.
Currently using ArcPy for my script and append query, but open to try other scripts like ogr2ogr or gdal if those are better.
I am using the following script:
import arcpy import os from arcpy.sa import * from sys import argv arcpy.env.workspace = "c:/workspace" out = "c:/workspace/out" schemaType = "NO_TEST" fieldMappings = "" subtype = "" featureclasses = arcpy.ListFeatureClasses(wild_card="NFS_PolySpatialJoin_*", feature_type='Polygon') for fc in featureclasses: print(fc) arcpy.Append_management(fc, out, schemaType, fieldMappings, subtype)
