I've heard of a user adding a separate section to the end of their
data-config.xml with a SqlEntityProcessor and an UPDATE statement. It would
run after your main section. I have not tried it myself, and surely
DIH was not designed to do this, but it might work.
A better solution might be t
Custom UpdateRequestProcessor that collects the IDs of submitted
documents and updates the database on commit.
DataImportHandler itself is strictly one-way read operation. But you
can add URP chain after it.
