code: public Stream<DTO> streamByIds(Set<String> idSet) {
          final List<ObjectId> objectIds = idSet.stream()
                  .map(ObjectId::new)

docs: Returns an unordered stream of all entries in the database for the given IDs.
  <p>
  The returned stream needs to be closed to free the underlying database resources.
  
  @param idSet set of IDs to query
  @return stream of database entries for the given IDs
