Subject Re: What is the recommended way to import and update index records?

What do you mean by "update"? If you mean partial update, DIH does not
do it AFAIK. If you mean replace, it should.

If you are getting duplicate records, maybe your uniqueKey is not set correctly?

clean=false looks to me like the right approach for incremental updates.
