--001a114dd2fe0c63b8053bd950ad Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable given mongodb is a document database, you may not want to try removing sub entities in such a way. You, imho, need to persist the aggregate as a whole. If you want to persist these sub entities separately, perhaps make them a separate aggregate. Repositories generally have aggregates persistested as a whole anyways, regardless of storage type, it's a good way to know when you have an aggregate.
