Update - I did manage to get the vast majority of the features to load - still missing 7,000/1,462,918 that showed errors during the LayerMapping process. I see a lot of "An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block." so I suspect there are fewer than 7,000 errors. I had "Step" set to 1,000. I imagine I can figure out how many errors there really are by setting "Step" to 1, This will get me started, but I am still very interested in further insight regarding my original question.
