Make insert on update (upsert: true) atomic with query + insert

    • Major Change

    Description

      The update operation (with upsert:true) is not currently atomic, for both the query + resulting insert. In highly active environments this will results in duplicated documents or an error due to unique index constraints.

      The preferred behavior is that all updates will insert a new document or update the existing one, and not result in duplicate documents.
