Hello @Evan Wellens ,
Thank you for posting query in Microsoft Q&A Platform.
Data Factory automatically generates an
_id
for a document if an_id
isn't specified either in the original document or by column mapping.
So, If you don't want ADF to generate _id
then you should consider column mapping or having _id
column in source.
Please Note, to achieve schema-agnostic copy, skip the "structure" (also called schema) section in dataset and schema mapping in copy activity.
