I ran topology errors on an entire database. Big mistake as the number of errors in this old legacy database is daunting. Can I rerun the topology errors on a smaller selected set of the database so that I can feel like I am accomplishing something
You should be able to re-validate the topology on the map extent; Validate a topology—ArcGIS Pro | Documentation
This will help you feel like you are making progress and slice down the errors into small chunks.
