This scheduled job (Export product feed incrementally) keeps Episerver Personalization up-to-date with product changes without exporting the entire catalog.
Because this job only exports added/updated products, it provides better performance and is faster than the Full Export Catalog Feed job. So, it can be run more frequently. But, the incremental job does not replace the Full Export Catalog Feed job because it excludes the deletion of products and edits to asset and inventory information.
