A job posting that is already deleted in my source, is still present as
= true in my destination
We do not capture deletes for the object OPPORTUNITY in our Lever connector. Objects that deletes are captured for are outlined in the Features section of the Lever Docs.
You can mark these as deleted by using this query in pseudocode as a guide for a transformation:
UPDATE opportunity SET _fivetran_deleted = true WHERE stage = '<opportunity_stage>';
