==> This will just add a new doc with two fields id:mydoc and price:99

==> if the atomic update logic sees a field with modifier in the supplied
doc, it treats the update as atomic (partial) update. So if your actual
doc has 10 fields and in your above example in addition to “id” and “price”
(with “set” modifier) you have a third field say “product” (without
modifier), it will be treated as a partial update and all 10 fields should
still be present post update (ofcourse with the new values for “price” and
“product”).
