Updating geometry in a feature class extremly slow

Discussion created by felix_arnet on May 12, 2015

I was stuck with the problem, that i needed to transform the geometries within a featureclass, that means no new featureclass could be created.


Everything in arcobjects worked fine till i wanted to stop the edit session, which took more than an hour for 10'000 features. Using updatecursors or just storing features did not make any difference.


Finally i found the simple solution: I had to drop the spatial index before doing the transformation, and recreate it afterwords. Now the stopEditing operation takes around a second.
