How to delete results from an AWS CLI DDB scan?

I made a model change that is now resulting in backwards incompatability issues. I want to go in and scan my ddb table for records created in the last couple days (I have a cli command that can do this), and then delete said records. Not sure how to easily merge the two processes together via an aws cli command, and going through all the records by hand and deleting them is a non-starter.

Is this a problem that AWS mi开发者_如何学Cght provide an easy way to solve that I'm just not seeing? Can't figure out how to import the scan results into some delete items call
